基于身份多接收者签密方案的安全性分析
Cryptanalysis of an identity-based multi-recipient signcryption scheme
摘要
Abstract
Identity-based multi-recipient signcryption(ID-MRSC)is an important cryptographic primitive which can simultaneously provide authenticity and privacy.In 2009,DU and WEN proposed an ID-MRSCheme,and claimed that their scheme satisfied the security requirements of confidentiality and unforgeability.This paper analyzed the scheme and presented a concrete attack against the scheme,indicating that the scheme fails to satisfy the security requirement of unforgeability.We presented a new ID-MRSC scheme that simultaneously satisfies the requirements of confidentiality and unforgeability.It's efficiency could be improved is our future work.关键词
