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。
Investigate a Diffie-Hellman key exchange protocol which is integrated into digital signature algorithm. Arzlyze 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.
