【摘要】 椭圆曲线上的公钥密码体制能够提供与其他公钥密码体制相同的安全性，而使用的密钥长度却要短得多。该文分析了几个基于椭圆曲线上的密钥共识协议，并提出了一个安全有效的三趟密钥共识协议。更多还原

【Abstract】 Elliptic curve groups is advantageous because it can provide equivalent security as the other group but with smaller key sizes and faster computation times, this paper analyzes the security of several key agreement protocols, and then presents a secure and efficient three- pass key agreement protocol.更多还原
