摘要: 电子商务环境面临许多安全性保障的要求,必须尽可能提供交易成员之间的保密性和可靠性。密钥管理提供一种服务,保证交易成员之间通信的安全,使其作为一个安全组进行协作。利用椭圆曲线密码(ECC)以及基于整数环的加法——乘法同态机制,提出一种同态密钥协商的新协议,该协议具有较高的安全性和较快的运算速度。

Abstract: There are various challenges in the electronic commerce environment.It is necessary to render members as autonomous and secure as possible.Key agreement is the service that ensures the security of communication among members,and the capability of their cooperation as a secure group.Making use of the additive-multiplicative homomorphism in the integer ring and ECC,a new protocols,called the homomorphism key agreement,is presented.It has better security,and its operation speed is more quickly.
