摘要
Abstract
This paper analyzes the self-certified multi-receiver signcryption scheme proposed by Wang Zhicang et al, and points out that attackers can forge new legal messages by public information, so that their scheme does not have the characteristic of unforgeability. Based on the discrete logarithm problem in finite field, this paper proposes an improved scheme by inserting the sender's private data into the encrypted session. Analysis result proves that the improved scheme can resist forgery attack, and has the characteristics of non-repudiation and confidentiality.关键词
