摘要
首先介绍目前数字化图书馆安全认证所面临的问题,然后在分析PKI、PMI的基础上提出了一个基于公开密钥证书和属性证书的双证书联合认证方案。其中使用公开密钥证书实现对用户的身份认证,属性证书实现用户的授权访问,能够保证不同用户具有不同的访问权限。该方案一定程度上满足了数字图书馆安全认证的要求,从而方便灵活地实现对数字资源的安全访问控制。
First, this paper briefly introduces problems in security certification of digiital library currently, and then proposes a dual certificate joint certification mechanism on the base of both public-key certificates and attribute certificates based on analyzing the PKI and PMI. The mechanism uses public key certificates to achieve user authentication, attribute certificate achieve the user＇s authodzed access, to ensure that different users have different access rights. A certain extent ,this mechanism meet with the requirements of Security Authenticate in Digital Library. Thereby, expediently and neatly realize security access control for digital resource.
