身份认证问题是网络安全的重要研究课题,利用椭圆曲线密码系统相对于其他公钥密码体制具有密钥长度短、运算速度快、计算数据量小的特点,结合X.509证书构建一个新的、高效的、安全的身份认证方案。
Identity authentication is the important problem in network security. Based on elliptic curve cryptosystem which showed ECC was shorter in key, faster in computing speed and less in data quantity than other public-key cryptosystems. This paper proposed an efficient and secure authentication scheme, which combined with X. 509 certification.
