The competition in cyberspace is ultimately the competition of talents.Nowadays,countries around the world pay great attention to the training of cyber security talents.the current situation of cyber security talents cultivation is introduced,the demand characteristics of cyber security talents are analyzed,and some suggestions for cyber security talents cultivation are put forward.Finally,some explorations on the training of cyber security talents in Jinan University are given.

In reality,universal blind steganalysis is still a sensitive issue.A universal online steganalysis system that could be used in practical application was proposed.With reducing the dimensions of SRM,it could improve availability and speed up feature extraction.Some effective pre-trained models and weighted voting strategy were used in this system with a B/S architecture,involving a higher speed.In addition,multithread technology was introduced.Experimental results demonstrate that high detection accuracy can be obtained and about 0.97 seconds for single detection with the system.

The rapid growth of digital image forensics calls for outsourcing digital forensics services to the cloud.It meets the requirement of image content authentication from both the public and organizations.However,it also brings the privacy concerns over the abuse of sensitive information.Based on the research in related fields,a digital forensics cloud platform with privacy preservation was presented.Furthermore,privacy-preserving outsourcing of three types of digital forensics methods,including copy-move detection,source identification and natural image sta-tistic-based tamper detection,were designed.Various future research directions were also discussed.

Big Data has attracted tremendous attention from all over the world nowadays.Its sheer volume,complex structure and realtime processing requirements often obsolete traditional technologies when coming to provide suffi-cient security protection.To address this challenge,significant research efforts have been carried out by the research community since recent years.Different technical aspects of big data security,including encryption algorithms,data integrity auditing,access control,secure data duplication,assured deletion,and secure search were surveyed,and in-depth discussions on their pros and cons were provided.Various future research directions were also discussed.

With the decreasing of the manufacturing cost and the development of technology, mini-drones are spreading from military and high-end commercial areas to civilian and consumer areas, and they have attracted great interests in recent years. On the one hand, mini-drones bring convenient, and on the other hand, they face with serious security problems. The research status of mini-drones, including the security threats of mini drones, the security attacks from mini drones, the authentication and traceability of mini drones, etc were introduced and analyzed. Finally, the future development of security research in mini-drones was also prospected.

Cyber security has been formally approved to be the first level discipline in June 2015.How to train the cyber security talents that meet the needs of our country has become an urgent problem to be solved in the discipline construction.Synthetical analysis of the current situation of training related talents at domestic and foreign,as well as the actual demand for the cyber security talents was presented.According to the characteristics of the talent culti-vation in cyber security,some suggestions on training the cyber security talents were given.

Recently,wearable devices acted as a kind of smart devices are changing people’s life style.When these devices are used in multi-user setting,ownership transfer should usually be considered.To resolve the security and privacy problems introduced in the ownership transfer process of wearable devices,a secure ownership transfer pro-tocol including initialization,mutual authentication and key change for wearable devices was introduced.The secu-rity analysis indicates that the proposed protocol can resist either normal channel attacks or special attacks appeared in the ownership transfer scenarios.The experiment results indicate that the proposed scheme is fairy efficient and is quite suitable for wearable devices.

With the massive diffusion of cloud computing,more and more sensitive data is being centralized into the cloud for sharing,which brings forth new challenges for the security and privacy of outsourced data.To address these challenges,the server-aided access control (SAAC) system was proposed.The SAAC system builds upon a variant of conditional proxy re-encryption (CPRE) named threshold conditional proxy re-encryption (TCPRE).In TCPRE,t out of n proxies can re-encrypt ciphertexts (satisfying some specified conditions) for the delegator (while up to t?1 proxies cannot),and the correctness of the re-encrypted ciphertexts can be publicly verified.Both features guarantee the trust and reliability on the proxies deployed in the SAAC system.The security models for TCPRE were formalized,several TCPRE constructions were proposed and that our final scheme was secure against chosen-ciphertext attacks was proved.
