摘　　要：基于椭圆曲线Diffie-Hellman问题,提出采用共享口令机制的基于椭圆曲线的可认证密钥协商协议(ECAKA),协议安全性依赖于椭圆曲线离散对数难题.该协议提供身份认证、密钥确认、完美前向安全性,并能够防止中间人攻击.An elliptic curve authenticated key agreement (ECAKA) protocol with pre-shared password, based on the elliptic curve Diffie-Hellman algorithm, was proposed, in which the security relied on the elliptic curve discrete logarithm problem (ECDLP). The protocol can provide identity authentication, key validation, perfect forward secrecy, and foil man-in-the-middle attacks.
