摘要： 现有数字版权管理系统不能完全满足数字媒体应用的安全性和灵活性要求，针对该问题，提出一种基于PKCS#12的数字版权管理系统，设计系统的体系结构和安全协议，包括用户注册、证书颁发、数字内容加密分发、许可证生成发放、认证和解密等功能。利用 PKCS#12的安全特点以及协议的安全性，实现用户证书和私钥的安全存储及转移，有利于用户跨设备参与系统应用，防止版权非法共享。

Abstract: Most of the existing Digital Rights Management(DRM) system can not meet the requirement of security and flexibility in digital media application. Aiming at this problem, this paper proposes a DRM system based on PKCS#12. It designs the system architecture and the security protocol of user registration, certificate issuing, encrypted digital content distribution, authorized license delivery, authentication and decryption, etc. With the security of PKCS#12 and the security of the designed protocols, the proposed system provides the secure storage and transfer of certificate and private key, lets users participate in system applications through different devices, and prevents digital rights from illegal sharing.

Key words: Digital Rights Management(DRM), PKCS#12, security protocol, license
