摘要
内容提供商、广播网络运营商和互联网络服务商从不同角度提出安全保证体系,但作为整个网络的技术解决方案,依靠目前任一个安全保证体系都可能无法保证各个层次的安全。若在一个网络同时采用多个安全体系,一方面会造成功能的重复浪费,另一方面也增加了系统的投资。以一个安全体系为主,在其上进行扩充在目前状况下不失为一个权宜之机。
With the convergence and mutual penetration of a variety of networks and the improvement of encryption and transmission technologies, the technologies of content protection, user protection and network transmission protection may also become converged. An analysis of working principle is made of CA system, DRM system and authentication management system, a comparison is made of technologies of various systems and the ideas of choosing security system under an interactive network is proposed.
