| 摘 要： | 本文提出了一种无第三方可信中心参与的数字版权安全协议。该协议采用数字内容和许可证各自单独封装、独立分发的方式,去掉传统DRM中的第三方,提高用户与服务器的交互效率。联机服务器注册、验证许可证,实现了数字产品动态分配许可权。协议交互中通过加密和数字签名保证分布式环境下数据的安全性和完整性。许可证采用自动销毁与更新的技术,保证版权免受克隆攻击和共谋攻击。

| Abstract: | A secure protocol for digital copyright protection without third-party is presented. This protocol makes digital content and license each package separately, and distribute independently, which gets rid of a third-party in the traditional DRM model, thus it can improve efficiency for both the client and the server. License is registered and checked by an online server, implementing the license dynamically allocated. Considering the integrity and security of the dynamic license, cryptography algorithms are u... |
