可实现授权控制与密钥加密独立的软件CA系统

摘要

In this paper, a CA system which independent the authorization and the key encryption under the software framework is introduced. The independence between ECM and EMM is shown. The whole working process is introduced and the process of authorization and the encryption of the control key are described in detail. The different characteristics between this CA system and the existing CA system are summarized.%在软件CA系统的框架下提出了一种将授权与密钥加密相独立的CA系统.阐述了这种系统的EMM与ECM独立的特性,描述了该套系统的工作过程,详细介绍了该系统的授权过程和对控制密钥解密的过程,总结了该系统与现有CA系统的不同的特点.
