用户验证方案设计

Design of User Authentication Scheme

利用Ｍ．Ｓ．Ｈｗａｎｇ提出的基于Ｅｉｇｍａｌ数字签名体制的用户远程口令验证方案作为基础，通过在网络系统的基层单位建立数据库，并由网络中央层对各数据项进行签名，实现了异地验证．并可以允许各子网络相互独立地选取秘密数据，为用户颁发证件，从而建立了一个规模不受限制。

Using the remote password authentication scheme proposed by M.S.Hwang,which is based on the Eigmal digital signature scheme,one identity authentication scheme was given.This is scale limitation free and each sub network′s safety is independent from each other.The main tools are the construction of database of the public datas of each basic unit and the technique of digital signatures.
