本文介绍了一种安全体系结构，允许在家庭网络中的数字版权管理的消费电子设备。这个想法是允许设备建立动态组，所谓的“授权域”，合法获得的版权内容可以在设备之间无缝移动。这大大改善了最终用户的体验，保留了“合理使用”的期望，并使内容提供商能够开发新的商业模式。我们的设计的关键是一个混合的合规性检查和组建立协议，基于预先分配的对称密钥，最小限度地依赖于公钥密码操作。我们的架构不需要设备之间的连续网络连接，并允许有效和灵活的密钥更新和撤销。
This paper describes a security architecture allowing digital rights management in home networks consisting of consumer electronic devices. The idea is to allow devices to establish dynamic groups, so called "Authorized Domains", where legally acquired copyrighted content can seamlessly move from device to device. This greatly improves the end-user experience, preserves "fair use" expectations, and enables the development of new business models by content providers. Key to our design is a hybrid compliance checking and group establishment protocol, based on pre-distributed symmetric keys, with minimal reliance on public key cryptographic operations. Our architecture does not require continuous network connectivity between devices, and allows for efficient and flexible key updating and revocation.
