“…Aiming at the problem of prolongation and instability of satellite and terrestrial physical communication links in the space-earth integration network,a two-way token based roaming authentication scheme was proposed.The scheme used the characteristics of the computing capability of the satellite nodes in the network to advance the user authentication process from the network control center (NCC) to the access satellite.The satellite directly verified the token issued by the NCC to verify the user's identity.At the same time,the token mechanism based on the one-way accumulator achieved the user's dynamic join,lightweight user self-service customization and billing,and the introduction of Bloom Filter enabled effective user revocation and malicious access management.Compared with the existing scheme,the scheme can guarantee the security of roaming authentication and significantly reduce the calculation and communication overhead of the authentication and key negotiation process.…”

Research on secret key generation based on wireless channel characteristics in body area network by Jingjing HUANG

“…Wireless body area network (WBAN) is a human-centered wireless network.With limitations of power and computation capabilities of WBAN, the significant challenge of ensuring security is how to generate a shared key between two entities based on a lightweight symmetric cryptography.To investigate this issue, a secret key generation scheme in ultra-wideband (UWB) WBAN was designed.In this scheme, the difference of multipath relative delay and its average value were chosen as common random source to reduce key mismatch probability.Furthermore, with the aid of relay, secret key generation rate could be increased.Simulation and test results demonstrate that the proposed scheme can achieve a good tradeoff between key match probability and key generation rate.Furthermore, security analysis of the scheme was also provided to validate its feasibility.…”

Research on HTML5 application cache poison attack by Yan JIA, He WANG, Shao-qing LYU, Yu-qing ZHANG

“…HTML5 application cache (AppCache) allowed Web browser to access Web offline.But it also brought a new method of cache poisoning attack that was more persisting.As for websites which used the AppCache,a novel poisoning method RFTM (replace file twice method),in which the attacker replaced the manifest file twice to poison the client’s AppCache,was proposed.Compared with the original attack,the legal server would not receive abnormal HTTP requests from the client in the attack.Therefore,changing the server configuration could not prevent the client from the RFTM AppCache poisoning.To avoid the attack mentioned above,a lightweight signature defense scheme Sec-Cache in application layer was designed.Furthermore,experiments show that it has good performance and compatibility.…”
