Abstract

Maintaining interconnectivity between dynamic vehicular nodes and ensuring trust in vehicular networking is still a challenging issue. It is crucial for the vehicular environments to maintain a stable interconnectivity between the vehicular nodes and further to prevent the vehicular nodes from broadcasting fake messages and simultaneously protect the vehicles against tracking attacks. An efficient Trust Management System (TMS) is proposed in this paper that will ensure trustworthiness and stable interconnectivity between vehicular entities to assure road safety and reliable communication. The proposed approach incorporates a novel timestamp mechanism and block chain concepts to ensure the steady inter-connectivity between the dynamic vehicular nodes. Further, the framework leverages block chain concepts to verify the correctness of the events stored in the Road Side Units (RSUs). It also proposes a versatile hybrid trust model that uses innovative direct and recommended trust evaluation techniques to compute trust between the vehicular entities. Moreover, the framework integrates a threading mechanism to schedule message execution in direct trust evaluation, and clustering techniques to group similar messages in indirect trust evaluation. Various experimental and comparative analyses with other related studies are carried out in a simulated environment to evaluate the performance of the proposed hybrid trust model. The findings show that the proposed trust model produces an accuracy of 92% in identifying malicious nodes. [ABSTRACT FROM AUTHOR]

Abstract

The vehicular network is a collection of vehicles and other components facilitated with versatile sensors to communicate, which is backboned by authentication. Present authentication protocols focus on either the lightweight feature or security. On the other hand, privacy during authentication is essential. Moreover, existing schemes are dependent on the trusted authority for checking the legitimacy of a communicating node, which suffers from the infrastructure-less scenario. Alternatively, existing protocols are dependent on a secure communication channel during the registration phase. To address these concerns, an elliptic curve cryptography-based authentication protocol has been designed. Moreover, a secure key establishment is shown in this paper. Pseudo-id-based authentication is used to provide the privacy-preservation on the scheme. On the other hand, symmetric-key cryptography with a session key is used for message encryption during communication. A security analysis on the proposed scheme using the BAN logic and AVISPA shows the protocol’s resilience capabilities on various attacks. Alternatively, the mathematical proof of the protocol represents the proof of correctness. Moreover, extensive performance analysis with the existing authentication schemes shows that the proposed algorithm is better in computation cost, communication cost, and energy cost. Lastly, the NS3 simulation shows the packet data transfer among the nodes in the network. [ABSTRACT FROM AUTHOR]

Abstract

Communication in vehicular ad hoc networks (VANETs) is significantly increased due to several services such as location-based service (LBS), traffic management, road safety, and vehicle privacy. Authentication is one of the backbones for communication in the vehicular network to protect the whole system, and guarantee the unforgeability and effectiveness of various services. On this note, in the above article, Nandy et al. (2021) recently proposed a secure, privacy-preserving, and lightweight authentication scheme for VANET. Recently, Chaudhry (2022) comments on Nandy et al.’s article, discussing the private-public key pair, clogging attack, and the pseudo-identity uses. This note addresses the raised comment by the aforesaid author. Furthermore, the detailed clarification against all comments is discussed with the purpose of producing a clear understanding.
