摘　　要：提出了一种适用于分布式计算环境的公钥认证系统．该系统中由用户产生的时戳代替一次性随机数解决了时间同步问题；以联网初始化协议代替键入口令，有效地防止了口令猜测和重放攻击．证书签发机构采用分级式管理，使系统可方便地实现群间认证和域间认证．This paper presents an authentication system based on asymmetric cryptosystem for the distributed environment. In this system, timestamps produced by the user instead of nonce are employed to solve the problem of time synchronization, and password login scheme is replaced by the initialization protocol, so guessing password attack and replay attack can be prevented effectively. A hierarchical organization for Certification Authority is employed, and then intercluster authentication and interdomain authentication can be achieved conveniently.
