摘　　要：在分析已有的Differ-Hellman两方密钥交换协议的基础上,提出了一种基于椭圆曲线的多方密钥协商协议,把椭圆曲线公钥密码体制运用于密钥协商的认证过程,能够有效地防止中间人攻击和重放攻击,保证了密钥协商协议的安全性和实用性.After analyzing of the existing Diffier-Hellman two parties key exchange protocol, a kind of multi-parties key agreement protocol based on elliptic curve was proposed. The intermediaries attack and replay attack can be effectively avoided and the security and practicability of the key agreement protocol were guaranteed when elliptic curve public-key cryptosystem was used in the key agreement authentication process.
