基于智能卡的远程口令认证方案的研究

基于RSA密码系统和安全单向的哈希函数,提出了一种相对安全的远程口令认证方案。采用个人身份识别码(PIN)与智能卡相结合的双因素认证方式,用户不但可以自主选取用户口令,而且还可以根据自身的需要随时更新口令,极大地增强了系统的安全性,提高了系统的认证效率。

Research of Remote Password Authentication Scheme Based on Smartcard

Based on the RSA cryptography and one-way secure hash function,this paper discusses a safer remote password authentication scheme with smart card.This scheme has the following advantages: Using the Double-Factor Authentication.Each user can freely choose his own password and can renew the password himself anytime according to his need.These will enhance the security of the system greatly and increase the efficiency of the authentication.
