摘要/Abstract

摘要： 研究一种集成DSA数字签名的DiffieHellman密钥协商协议，对Phan改进协议进行安全性分析和优化。然后，基于RSA-OAEP密钥算法设计了一种新的密钥协商协议。该协议形式简单，计算速度快，并满足密钥协商协议所需的安全属性。

Abstract: Investigate a Diffie-Hellman key exchange protocol which is integrated into digital signature algorithm.Analyze Phan’s improved protocol and give a further improvement.Then a novel key exchange protocol based on RSA-OAEP cryptosystem is presented.The protocol is simple，efficient and can provide standard security attributes that key exchange protocols should have.

Key words: key exchange protocol, DSA, RSA-OAEP
