Witryna1 lut 2010 · The proposed certificateless signcryption scheme In this section, we propose a certificateless signcryption scheme secure against malicious-but-passive KGC attacks in the standard model. The proposed scheme involves three parties: a KGC, a sender with an identity u S and a receiver with an identity u R. WitrynaSeveral signcryption schemes proposed in the literature are known to lack semantic security, and semantically secure signcryption schemes tend to be more computationally expensive. In fact, devising an efficient signcryption scheme providing both public verifiability and forward security was until now an open problem. In this … WitrynaIdentity-based signcryption was rst proposed by Malone-Lee [51], and was then intensively studied thereafter (e.g., [20,26,11,8]). The reader is referred to [43] for a good survey on ID-based signcryption. Identity-based signcryption has numerous promising applications. For example, it is used in secure and privacy- pope benedict hand
