【Abstract】 This paper analyzes the security of existing WTLS handshake protocol and points out the secure limitation and its corresponding threat. Then we propose a modified WTLS handshake protocol which can provide forward secrecy and user anonymity by using signcryption. Finally this paper makes a discussion of the security of modified protocol.更多还原
