摘　　要：身份验证是网络环境下的关键环节之一。基于椭圆曲线密码体制的成绩录入系统身份验证,对通信双方进行基于椭圆曲线的数字签名的双向身份认证,安全性由椭圆曲线离散对数问题保证,同时降低了密钥量。通过对其中关键的平方剩余判定算法进行优化,提高了整个ECC算法的效率,在运算速度和存储空间方面相对其他身份认证方案有较大优势。Identity authentication is an important step in network. This paper presents a algorithm for score input system based on elliptic curve, which implements the dual direction identity authentication. The discrete logarithm problem of elliptic curve ensures system security, at the same time has a small key. In additional the whole ECC algorithm has a good efficiency because the algorithm for square overplus judging has been optimized. The algorithm in this paper has a better display on speed and storage space than the other identity authentication methods.
