【摘要】 为实现移动通信中收发双方相互的认证,提出了一种具有前向安全性能的新签密方案.分析结果表明,新方案不但保留了椭圆曲线密码体制特有的优越特性,并且满足了目前一些现存签密方案都无法提供的前向安全性需求.当发送方和接收方发生争议时,可以交由公平第3方,即仲裁者去仲裁解决.更多还原

【Abstract】 A new sign-cryption scheme with the feature of forward secrecy was presented in order to realize the authentication during the procedure of mobile communication.The analysis result of scheme shows that superiority in efficiency and secrecy of elliptic curve system has been maintained exactly,the new scheme is sufficient to the forward secrecy unlike those sign-cryption schemes in existence.If two parties in the communication crash with each other,the third one will solve the problem,it means the arbiter.更多还原
