【摘要】 首先介绍Kerberos的认证过程,特别是分析Kerberos认证协议的局限性。然后采用RSA加密算法的一种Yaksha改进算法,给出一种公钥认证协议。这种协议由用户验证自己产生的时间戳,这样就解决了时间同步的问题,并且克服了Kerberos的某些局限性。更多还原

【Abstract】 This paper Firstly has introduced authentification process of kerberos system. Specially, pointed out its insufficiency.Then an authentification protocol was offered based on public key .The protocol adopted RAS improved through Yaksha arithmetic. At the protocol users validate timestamp themselves. Therefore, synchronization problem is resolved, and insufficiency of kerberos system is overcome.更多还原
