Due to an explosive growing demand for higher data rates that have led to the 5th generation of mobile networks, Network Coding-enabled mobile small cells are observed as a promising technology for 5G networks that can cover the urban landscape by being set up on-demand at any place, and at any time on any device. Despite the benefits of network coding technology on these networks, pollution attacks should be addressed before network coding technology reaches its full potential in 5G mobile small cells. In this paper, we have proposed an intrusion detection and prevention scheme which is able not only to detect and prevent pollution attacks but also to detect the exact location of adversary nodes which are the source of pollution attacks.

Objectives Diabetic patients who undergo lower limb arterial bypass surgery are considered to have a worse clinical outcome compared to non-diabetics. The aim of the study was to test this hypothesis after applying propensity score matching analysis. Patients and methods A total of 113 consecutive lower limb bypass procedures (55 diabetic and 58 non-diabetic) were evaluated regarding their clinical outcome. Endpoints of the study included amputation-free survival, limb salvage, patency and patients’ survival up to 36 months post-procedure. After propensity score matching analysis, two new groups, diabetic and non-diabetic, of 31 limbs in each one were created, both equivalent regarding all baseline characteristics. Results Between the propensity score matching groups, the amputation-free survival was 68.8% in the non-diabetic and 37.7% in the diabetic group at 36 months ( p = 0.004). Similarly, the survival was 88.6% and 57.6%, respectively, in the two groups at the same time point ( p = 0.01). On the contrary, no difference was found in patency (58.3% vs. 56%) and in limb salvage rate (74.1% vs. 60.8%). Conclusions Lower limbs arterial bypass surgery has similar results regarding patency and limb salvage rate in diabetic and non-diabetic patients. On the contrary, mortality is worse in diabetic patients, this affecting negatively their amputation-free survival.

This paper proposes a security framework for secure data communications across the partners in the Semiconductor Supply Chain Environment. The security mechanisms of the proposed framework will be based on the SSL/TLS and OAuth 2.0 protocols, which are two standard security protocols. However, both protocols are vulnerable to a number of attacks, and thus more sophisticated security mechanisms based on these protocols should be designed and implemented in order to address the specific security challenges of the Semiconductor Supply Chain in a more effective and efficient manner.

Exploiting physical layer in achieving different security aspects in wireless communications has been widely encouraged. In this work, the authors propose an entity authentication scheme for mobile devices with multiple antennas, which is purely based on physical layer parameters. According to the proposed scheme, in order to authenticate a device, a number of predefined authentication signals should be detected at the receive antennas on the authenticator side. The transmitted signals are designed based on the instantaneous channel responses in order to deliver the authentication signals to the receiver. The proposed scheme works efficiently even for mobile users, which is considered a significant improvement over previous related works. Mathematical analysis of the different involved factors along with sufficient simulations show the high performance of the proposed authentication scheme.

Privacy preservation is of paramount importance in the emerging smart city scenario, where numerous and diverse online services will be accessed by users through their mobile or wearable devices. In this scenario, service providers or eavesdroppers can track users’ activities, location, and interactions with other users, which may discourage citizens from accessing smart city services. Pseudonym-based systems have been proposed as an efficient solution to provide identity confidentiality, and more concretely pseudonym-based signature schemes have been suggested as an effective means to authenticate entities and messages privately. In this paper we describe our implementation of a pseudonym-based signature scheme, based on bilinear-pairings. Concretely, our implementation consists of an Android application that enables users to authenticate messages under self-generated pseudonyms, while still enabling anonymity revocation by a trusted third party in case of misbehavior. The paper presents a description of the implementation, performance results, and it also describes the use cases for which it was designed.

In last 30 years, the endovascular aneurysm repair (EVAR) has become the standard method of treatment of abdominal aortic aneurysms (AAAs). Nevertheless, the method has limitations mainly based on the anatomic characteristics of the specific aneurysm. In these cases, a combination of endovascular and open techniques can be used. We describe a case of a patient with an infrarenal AAA and an ectopic right renal artery emerging from within the aneurysm sac. The patient was treated with a combination of endovascular and open techniques. In particular, he underwent a hepatorenal revascularization followed by a standard EVAR procedure, with a successful final outcome. For the treatment of AAA disease, the combination of open and endovascular procedures can overcome difficulties, where a standard EVAR cannot be an option.

The continuous growth in wireless devices connected to the Internet and the increasing demand for higher data rates put ever increasing pressure on the 4G cellular network. The EU funded H2020-MSCA project “SECRET” investigates a scenario architecture to cover the urban landscape for the upcoming 5G cellular network. The studied scenario architecture combines multi-hop device-to-device (D2D) communication with network coding-enabled mobile small cells. In this scenario architecture, mobile nodes benefit from high transmission speeds, low latency and increased energy efficiency, while the cellular network benefits from a reduced workload of its base stations. However, this scenario architecture faces various security and privacy challenges. These challenges can be addressed using cryptographic techniques and protocols, assuming that a key management scheme is able to provide mobile nodes with secret keys in a secure manner. Unfortunately, existing key management schemes are unable to cover all security and privacy challenges of the studied scenario architecture. Certificateless key management schemes seem promising, although many proposed schemes of this category of key management schemes require a secure channel or lack key update and key revocation procedures. We therefore suggest further research in key management schemes which include secret key sharing among mobile nodes, key revocation, key update and mobile node authentication to fit with our scenario architecture.

In the emerging industrial Internet of Things (IIoT) era, machine-to-machine (M2M) communication technology is considered as a key underlying technology for building IIoT environments, where devices (e.g., sensors, actuators, and gateways) are enabled to exchange information with each other in an autonomous way without human intervention. However, most of the existing M2M protocols that can be also used in the IIoT domain provide security mechanisms based on asymmetric cryptography resulting in high computational cost. As a consequence, the resource-constrained IoT devices are not able to support them appropriately and thus, many security issues arise for the IIoT environment. Therefore, lightweight security mechanisms are required for M2M communications in IIoT in order to reach its full potential. As a step toward this direction, in this paper, we propose a lightweight authentication mechanism, based only on hash and XOR operations, for M2M communications in IIoT environment. The proposed mechanism is characterized by low computational cost, communication, and storage overhead, while achieving mutual authentication, session key agreement, device's identity confidentiality, and resistance against the following attacks: replay attack, man-in-the-middle attack, impersonation attack, and modification attack.

Smart grid introduces a wealth of promising applications for upcoming fifth-generation mobile networks (5G), enabling households and utility companies to establish a two-way digital communications dialogue, which can benefit both of them. The utility can monitor real-time consumption of end users and take proper measures (e.g., real-time pricing) to shape their consumption profile or to plan enough supply to meet the foreseen demand. On the other hand, a smart home can receive real-time electricity prices and adjust its consumption to minimize its daily electricity expenditure, while meeting the energy need and the satisfaction level of the dwellers. Smart Home applications for smart phones are also a promising use case, where users can remotely control their appliances, while they are away at work or on their ways home. Although these emerging services can evidently boost the efficiency of the market and the satisfaction of the consumers, they may also introduce new attack surfaces making the grid vulnerable to financial losses or even physical damages. In this paper, we propose an architecture to secure smart grid communications incorporating an intrusion detection system, composed of distributed components collaborating with each other to detect price integrity or load alteration attacks in different segments of an advanced metering infrastructure.

A 71-year-old male patient with severe left buttock and lower-extremity claudication due to iliac artery bifurcation stenoses was referred to our institution for endovascular treatment. A ‘kissing’ technique was used in order to dilate the proximal parts of both internal and external iliac arteries and avoid compromization of the internal iliac artery during proximal external iliac artery stenting. A balloon expandable stent was inserted via a left ipsilateral retrograde access to the narrowed origin of the left external iliacartery and a balloon catheter via a right contralateral access inside the origin of the left internal iliac artery. Simultaneous balloons inflation restored full patency of both vessels. Twelve months later the patient is doing well, free of buttock or lower-extremity claudication symptoms. For iliac artery bifurcation atherosclerotic disease, endovascular repair with the ‘kissing’ technique can achieve a complete bifurcation reconstruction offering significant clinical benefit in selected patients.

In the forthcoming Smart City scenario, users' mobile applications will be of fundamental role towards supporting the envisioned functionalities and services. Mobile users, provided with a smartphone, will be capable of ubiquitously connecting to service providers through their installed mobile applications. However, this connection must be authenticated, which threatens the citizen privacy rights. Privacy-preserving mechanisms have already been proposed in the past; nevertheless, they are based on RSA groups or groups with bilinear pairings, which are inefficient in mobile devices due to its computational complexity. Thus, in this paper, we integrate a lightweight anonymous credential mechanism, suitable for computationally-limited mobile devices, into the user authentication phase of the OAuth2 protocol, which has become a de facto solution for user authentication in mobile applications. The proposed protocol enables citizen's authentication towards service providers, while preserving their privacy. Additionally, the protocol is compliant with the OAuth2 specification, which enables an easy integration in current mobile application implementations.

Industry 4.0 considers integration of IT and control systems with physical objects, software, sensors and connectivity in order to optimize manufacturing processes. It provides advanced functionalities in control and communication for an infrastructure that handles multiple tasks in various locations automatically. Automatic actions require information from trustworthy sources. Thus, this work is focused on how to ensure trustworthy communication from the edge devices to the backend infrastructure. We derive a meta-model based on RAMI 4.0, which is used to describe an end-to-end communication use case for an Industry 4.0 application scenario and to identify dependabilities in case of security challenges. Furthermore, we evaluate secure messaging protocols and the integration of Trusted Platform Module (TPM) as a root of trust for dataexchange. We define a set of representative measurable indicator points based on existing standards and use them for automated dependability detection within the whole system.

The challenge for fast and low-cost deployment of ubiquitous personalized e-Health services has prompted us to propose a new framework architecture for such services. We have studied the operational features and the environment of e-Health services and we led to a framework structure that extends the European Telecommunications Standards Institute (ETSI)/Parlay architecture, which is used for the deployment of standardized services over the next generation IP networks. We expanded the ETSI/Parlay architecture with new service capability features as well as sensor, profiling, and security mechanisms. The proposed framework assists the seamless integration, within the e-Health service structure, of diverse facilities provided by both the underlying communication and computing infrastructure as well as the patient's bio and context sensor networks. Finally, we demonstrate the deployment of a telemonitoring service in smart home environment based on the proposed framework architecture.

Cloud radio access networks (C‐RAN) are a promising technology that will allow the new generation of 5G mobile communication systems to address the industry's capacity growth needs and demands for higher mobility. At the same time, energy‐efficient operation will be delivered together with operating and capital cost savings. However, despite the significant benefits of C‐RAN technology in 5G mobile communication systems, it has to face multiple inherent security challenges associated with virtual systems and cloud computing technology, which may hinder its successful establishment in the market. Thus, it is critical to address these challenges to enable C‐RAN technology to reach its full potential and foster the deployment of future 5G mobile communication systems. Therefore, this chapter presents representative examples of possible threats and attacks against the main components of the C‐RAN architecture in order to shed light on the security challenges of C‐RAN technology and provide a roadmap to ensure security in this emerging technology.

In the context of the Smart City concept, mobile e-Health applications can play a pivotal role towards the improvement of citizens' quality of life, since they can enable citizens to access personalized e-Health services, without limitations on time and location. However, accessing personalized e-Health services through citizens' mobile e-Health applications, running on their mobile devices, raises many privacy issues in terms of citizens' identity and location. These privacy issues should be addressed so that citizens, concerned about privacy leakage, will embrace Smart City mobile e-Health applications and reap their benefits. Hence, in this paper we propose an OAuth2-based protocol with strong user privacy preservation that addresses these privacy issues. Our proposed protocol follows the OAuth2 protocol flow and integrates a pseudonym-based signature scheme and a delegation signature scheme into the user authentication phase of the OAuth2 protocol. The proposed protocol enables citizens authentication towards the servers providing personalized e-Health services, while preserving their privacy from malicious mobile applications and/or eavesdroppers. Moreover, the proposed protocol does not require to store sensitive information in the citizens' mobile devices.1

This letter proposes an efficient null space-based homomorphic message authentication code scheme providing resistance against tag pollution attacks in random linear network coding, where these attacks constitute a severe security threat. In contrast to data pollution attacks, where an adversary injects into the network corrupted packets, in tag pollution attacks the adversary corrupts (i.e. pollutes) tags appended to the end of the coded packets to prevent the destination nodes from decoding correctly. Our results show that the proposed scheme is more efficient compared to other competitive tag pollution immune schemes in terms of computational complexity.

Network Coding has significantly shown the achievable throughput and robustness in wireless Networks. However, network coding-enabled networks are susceptible to pollution attacks where a small number of polluted messages will propagate due to recoding and corrupt bunches of legitimate messages. Several lightweight Homomorphic Message Authentication Code (HMAC) schemes have been proposed for protecting the transmitted data against pollution attacks; however, most of them are not appropriate for wireless networks or cannot resist tag pollution attacks. In this paper, we present a computationally efficient null space-based homomorphic MAC scheme, for network coding-enabled wireless networks. The proposed scheme makes use of two types of tags (i.e., MACs and D-MACs) to provide resistance against data pollution and tag pollution attacks. Furthermore, we demonstrate that due to its lightweight nature, our proposed scheme incurs a minimal complexity compared to other related schemes.

Network coding has shown a considerable improvement in terms of capacity and robustness compared to traditional store-and-forward transmission paradigm. However, since the intermediate nodes in network coding-enabled networks have the ability to change the packets en route, network coding-enabled networks are vulnerable to pollution attacks where a small number of polluted messages can corrupt bunches of legitimate messages. Recently, research effort has been put on schemes for protecting the transmitted messages against data pollution attacks. However, most of them cannot resist tag pollution attacks. This paper presents a new homomorphic MAC-based scheme, called Dual-Homomorphic MAC (Dual-HMAC), for network coding-enabled wireless sensor networks. The proposed scheme makes use of two types of tags (i.e., MACs and D-MACs) to provide resistance against data pollution attacks and partially tag pollution attacks. Furthermore, our proposed scheme presents low communication overhead and low computational complexity compared to other existing schemes.

The increasing threat of Denial of Service (DoS) attacks targeting Smart City systems impose unprecedented challenges in terms of service availability, especially against centralized control platforms due to their single point of failure issue. The European ARTEMIS co-funded project ACCUS (Adaptive Cooperative Control in Urban (sub) Systems) is focused on a centralized Integration and Coordination Platform (ICP) for urban subsystems to enable real-time collaborative applications across them and optimize their combined performance in Smart Cities. Hence, any outage of the ACCUS ICP, due to DoS attacks, can severely affect not only the interconnected subsystems but also the citizens. Consequently, it is of utmost importance for ACCUS ICP to be protected with the appropriate defense mechanisms against these attacks. Towards this direction, the measurement of the performance degradation of the attacked ICP server can be used for the selection of the most appropriate defense mechanisms. However, the suitable metrics are required to be defined. Therefore, this paper models and analyzes the impact of DoS attacks on the queue management temporal performance of the ACCUS ICP server in terms of system delay by using queueing theory.

Public Protection and Disaster Relief (PPDR) agencies in European member states currently rely on digital Private Mobile Radio (PMR) networks for mission critical operations. PMR networks are based on two main standards for Europe: Terrestrial Trunked Radio (TETRA) and TETRAPOL. These networks provide secure and resilient mobile voice services, as well as basic data services. However, these traditional PMR networks show substantial limitations, when matched against modern requirements of PPDR agencies, including broadcast communications, dynamic secure groups, secure roaming, and emerging safety and security applications. Moreover, there are significant interoperability constraints when using multiple technologies, such as inter-technology coverage limitations, which can result in ineffective management of emergency events, both at national level as well as in cross-border regions.

Security has recently become an important issue that needs to be addressed in an era where governments are investing heavily into preventive measures against cyber-crime that includes denial of service attacks, tampering attacks and eavesdropping attacks, among others. These types of malpractice are foreseen as threats in future 5G scenarios, since confidential information will be downloaded, uploaded and processed via the upcoming 5G systems. Furthermore, the emergence of the 5G era requires the integration of multiple existing advanced technologies with innovative new techniques, which will result in many security breaches. Thus, in this chapter, we present representative examples of potential threats and attacks against the main components of 5G systems in order to shed light on the future security issues and challenges in the upcoming 5G era.

Homomorphic Message Authentication Code (HMAC) is a low-complexity low-delay scheme for pollution detection is a Random Linear Network Coding (RLNC) enabled network. However, HMAC is vulnerable to tag pollution, in which an adversary node merely randomly modifies some MAC tags appended at the end of data packets. Existing tag pollution resistant solutions cause either high computation efforts long delay at relay nodes or substantial communication burden, or additional requirements such as synchronization at all nodes. In this paper, we combine the core ideas of two pollution detection schemes: “padding for orthogonality” and “Null key”, and propose a new pollution detection method by “jointly padding for subspace orthogonality” that is immune to tag pollution, remains low-complexity low-delay, low communication overhead, and no timing requirements.

In healthcare, trust is considered to be the key factor for the provision of effective healthcare services. Thus, ubiquitous healthcare environment incorporate Trust Management systems or services for enabling the creation of confident and secure background required for the provision of healthcare services. In this paper the concept of personalized Trust Management service is introduced. However, since this approach makes the service vulnerable to user's subjectivity in this paper is proposed a mechanism that determines the proper in case personalization factor. Especially, it quantifies the Quality of trust Information that user has acquired from past interactions and determines if he/she is capable to discover and select healthcare providers. The introduced mechanism is deployed on a Fuzzy Interference System and its performance was evaluated through simulations in MATLAB/SIMULINK environment.

Healthcare services are designed for enabling the provision of medical care to the patient. The traditional healthcare services are based on the doctor-centric paradigm. Essentially, they enable healthcare providers to assess patients’ health status based on information derived from medical examination and information stored in patient’s electronic Medical Health Records (eMHRs) [1]. Hence, it is crucial for patient’s health data to be digitalized and organized in such a way allowing their exploitation by the healthcare provider at a later point of time [2]. The doctor-centric healthcare services enhance healthcare providers’ diagnosing skills and enable them to give patients accurate treatment directions aiming to their earlier and safer de-hospitalization.

Ubiquitous Healthcare environment materializes the patient-centric paradigm providing healthcare services without spatial and temporal limitations. However, the nature of Ubiquitous Healthcare services requiring exchange of sensitive personal data raises trust issues. In this paper, we propose a profile-based Trust Management scheme that enables the patient to select the most trustworthy Healthcare Provider in a Ubiquitous Healthcare environment. Furthermore, we propose an extended User Profile structure integrating trust-related information in order to enhance the functionality of the proposed Trust Management scheme.

Nowadays, the personalization in ubiquitous healthcare is of utmost importance for enabling the provision of services tailored to the patient’s needs and interests. The personalization of the ubiquitous healthcare services is based on the profiles of the entities participating in these services. Such an application is the dynamic creation of the group of the entities that is formed to deliver the healthcare service to the patient. In this paper, we propose an approach for achieving creation of group profiles in a ubiquitous healthcare environment applying the Analytic Hierarchy Process.

For iliac artery bifurcation atherosclerotic disease, endovascular repair with the kissing’ technique can achieve a complete bifurcation reconstruction offering significant clinical benefit in selected patients.

Nowadays, ubiquitous healthcare is of utmost importance in the patient-centric model. Furthermore, the personalization of ubiquitous healthcare services plays a very important role to make the patient-centric model a reality. The personalization of the ubiquitous healthcare services is based on the profiles of the entities participating in these services. In this paper, we propose a group profile management system in a ubiquitous healthcare environment. The proposed system is responsible for the dynamic creation of a group profile and its management.

In this paper, a Polymorphic Encryption Algorithm (PEA), based on basic quantum computations, is proposed for the encryption of binary bits. PEA is a symmetric key encryption algorithm that applies different combinations of quantum gates to encrypt binary bits. PEA is also polymorphic since the states of the shared secret key control the different combinations of the ciphertext. It is shown that PEA achieves perfect secrecy and is resilient to eavesdropping and Trojan horse attacks. A security analysis of PEA is also described.

Nowadays, there is a significant lack of generic application frameworks providing third party developers with the appropriate mechanisms for building ubiquitous context-aware healthcare applications over medical heterogeneous networks. In this paper, we propose a new framework integrating context-aware and security mechanisms with mechanisms that allow the ease exploitation of the core networks' functionality to enable third party developers to build reliable and secure ubiquitous context-aware healthcare applications over medical heterogeneous networks.

This chapter presents the concept of Smart Home, describes the Smart Home networking technologies and discusses the main issues for ensuring security in a Smart Home environment. Nowadays, the integration of current communication and information technologies within the dwelling has led to the emergence of Smart Homes. These technologies facilitate the building of Smart Home environments in which devices and systems can communicate with each other and can be controlled automatically in order to interact with the household members and improve the quality of their life. However, the nature of Smart Home environment, the fact that it is always connected to the outside world via Internet and the open security back doors derived from the household members raise many security concerns. Finally, by reviewing the existing literature regarding Smart Homes and security issues that exist in Smart Home environments, the authors envisage to provide a base to broaden the research in Smart Home security.

During the past few years a lot of PKI (Public Key Infrastructures) infrastructures have been proposed for healthcare networks in order to ensure secure communication services and exchange of data among healthcare professionals. However, there is a plethora of challenges in these healthcare PKI infrastructures. Especially, there are a lot of challenges for PKI infrastructures deployed over large-scale healthcare networks. In this paper, we propose a PKI infrastructure to ensure security in a large-scale Internet-based healthcare network connecting a wide spectrum of healthcare units geographically distributed within a wide region. Furthermore, the proposed PKI infrastructure facilitates the trust issues that arise in a large-scale healthcare network including multi-domain PKI infrastructures.

Ad hoc networks are dynamic peer-to-peer wireless networks composed of a collection of nodes which employ wireless transmission methods in a self-organized way without relying on fixed infrastructure or predetermined connectivity. Such networks pose great challenges in group communication. In this paper, we propose an efficient group key agreement and recovery mechanism based on key escrow systems for ad hoc networks. Nodes randomly change their operation and perform authentication services for specific groups.

During the past few years, a lot of effort has been invested in research and development of eHealth tele-monitoring systems that will provide many benefits for healthcare delivery from the healthcare provider to the patient's home. However, there is a plethora of security requirements in eHealth tele-monitoring systems. Data integrity of the transferred medical data is one of the most important security requirements that should be satisfied in these systems, since medical information is extremely sensitive information, and even sometimes life threatening information. In this paper, we present a data integrity mechanism for eHealth tele-monitoring system that operates in a smart home environment. Agent technology is applied to achieve data integrity with the use of cryptographic smart cards. Furthermore, the overall security infrastructure and its various components are described.

We consider an environment strongly affected by the presence of metallic objects, that can be considered representative of an indoor industrial environment with metal obstacles. This scenario is a very harsh environment where radio communication has notorious difficulties, as metallic objects create a strong blockage component and surfaces are highly reflective. In this environment, we investigate how to dynamically allocate MAC resources in time to static and mobile users based on context awareness extracted from a legacy WiFi positioning system. In order to address this problem, we integrate our WiFi ranging and positioning system in the WiSHFUL architecture and then define a hypothesis test to declare if the link is in line-of-sight (LOS) or non-line-of-sight (NLOS) based on angular information derived from ranging and position information. We show that context information can help increase the network throughput in the above industrial-like scenario.
