| 摘 要： | 针对密钥建立协议SKA存在临时密钥泄漏攻击和缺乏前向保密性的问题，提出一个高效的基于签密的可认证密钥协商协议。通过在CDH假设下利用椭圆曲线密码体制，将长期私钥和临时私钥混合的方法来保证协议安全，并在此基础上实现协议的相互认证和密钥确认功能。分析结果表明，该协议的效率和安全性提高明显。

| Abstract: | The key establishment protocol(called SKA) can not resist known temporary key and forward secrecy.Aiming at this problem,an efficient authenticated key agreement protocol based on signcryption is proposed.The proposed protocol uses elliptic curve cryptosystem technology under the computational Diffie-Hellman assumption,combines the long private key and short private key and implements the functions of mutual authentication and key confirmation.Analysis result proves that the efficiency and security of the p... |
