摘要
根据公钥密码技术，提出了一种适用于公用网系统的用户存取控制方案。该方案假设网中用户持有由可信任的认证中心（ＴＡＣ）发行的个人卡──记忆卡式智能卡。无论是记忆卡还是智能卡的认证协议，均可避免使用公钥簿，使公用网中的用户存取控制更加安全和方便。
Based on public key cryptographic techniques,this peper presents a secure user access control scheme for public networks. The scheme assumes that each user has a personalized card-memory card or smart card issued by a trusted authentication center. Both authentication protocol with memory card and with smart card can avoid using public key directory. Thus,user access control for public networks is more secure and convenient. For the smart card,it is shown that user's secrets need not be exposed to the trusted authentication center.
