摘要
数字作品的版权保护其本质是对作品的远程持久访问控制。SPKI/SDSI是一种注重实现分布式系统的安全访问控制的PKI系统。文章提出了利用SPKI/SDSI证书实现数字版权保护系统中的身份认证、权限控制和密钥传递等功能。并依此提出了新的安全访问控制协议。
The essence of the Internet content copyright protection system is that the owner of the content could control the use of the content remotely,securely and persistently. SPKI/SDSI is a PKI system for distributed secure access control. This paper describes an Internet content copyright protection system using SPKI/SDSI certificates. The system achieves authentication、right controlling and the key transfer by using SPKI/SDSI certificates. A new security access control protocol has also been brought forward.
