Abstract

Abstract: With the implementation and developing of the Push VOD system, there are more and more challenges to the digital content protection technology. Traditional Conditional Access（CA） technology can not satisfy the security requirement of the Push VOD system. In this paper, combined with existing Digital Right Management（DRM）, a Push VOD DRM system design scheme is given. In this system, DRM technology will be integrated with CA technology, the key management of the entire system will be in-depth study, and the throughout the life cycle of digital content protection is realized, which meets the security needs of Push VOD system. By the way, It supports services provided for Push VOD system.

Key words: Push VOD, Digital Right Management（DRM）, Conditional Access（CA）, key management

摘要： Push VOD系统的推行和发展给数字内容保护技术带来了更大的挑战，传统的条件接收技术已不能满足Push VOD系统的安全性需求。结合现有数字版权保护技术，提出了一种Push VOD DRM系统的设计方案。该系统将DRM技术与CA技术融合，对整个系统的密钥管理逻辑进行了深入的研究，实现对数字内容整个生命周期的保护，满足了Push VOD系统的安全性需求，也为Push VOD系统提供了付费业务的支撑。
