In this paper, we propose a novel in-situ pair-wise key establishment scheme based on master key updating and knowledge of post deployment for large-scale distributed wireless sensor networks. Our scheme aims at achieving a satisfying key sharing probability among sensors with low memory overhead. Our scheme employs location information of post deployment(More)

A number of self-healing group key distribution schemes have been proposed recently, however, though practicality analysis and simulation of the commonly used self-healing group key distribution schemes, we show that almost none of the existing schemes are suitable for large-scale and resource-constricted wireless sensor networks in real-world applications,(More)
A great many algorithms of video encryption have been proposed nowadays with the necessity of data rights management, especially the selective video encryption algorithms, which ensure the security of the information and meanwhile reduce the data to encrypt. The residue data, intra-prediction modes, inter-prediction modes and motion vectors are key elements(More)
Physical-layer authentication can address physical layer vulnerabilities and security threats in wireless sensor networks, and has been considered as an effective complementary enhancement to existing upper-layer authentication mechanisms. In this paper, to advance the existing research and improve the authentication performance, we propose a novel physical(More)
—The self-healing group key distribution with revocation can deal with the session key distribution problem for secure group communication over an unreliable wireless network, with the capability of resistance to the packet loss and the collusion attack. However, since previous self-healing group key distribution schemes are restricted to m sessions, they(More)
