This paper presents a distributed user authentication scheme in wireless sensor networks. Our scheme is based on the self-certified keys cryptosystem (SCK), and we have modified i...
In this paper we propose an improved and efficient key pre-distribution scheme for wireless sensor networks. Our scheme significantly increases the storage efficiency and security...
In 2004, Sekhar proposed a new signature scheme with message recovery. Based on this signature scheme with message recovery, they also proposed a designated verifier signature sch...
In this paper a class of subdivision schemes generalizing the algorithm of Loop is presented. The stencils have the same support as those from the algorithm of Loop, but allow a v...
In ACM Multimedia’2002, a video proxy scheme was proposed for secure video delivery. In the scheme, a video is cached in proxies in encrypted form so that it remains nondisclose...
