基于数字签名方案的口令鉴别方案

PASSWORD AUTHENTICATION SCHEMES BASED UPON DIGITAL SIGNATURE SCHEMES

本文在广义ＥｌＧａｍａｌ型签名方案上建立了许多口令鉴别方案，并且提出了文［１］的三个改进方案。利用这些方案，计算机系统不仅能监测和控制口令的使用，而且可以抗击许多对口令的伪造攻击。

In this paper,many new remote password authentication schemes are proposed based on generalized ElGamal type digital signature schemes.In addition,three improved schemes of paper are presented.By using these schemes,computer system can not only supervises and controls all passwords,but also withstand all attack of forging password.
