基于证书认证的安全多媒体会议系统MCS/CA的设计与实现

The Design and Implementation of a Certificate-based Secure Multimedia Conference System MCS/CA

文章综述了CSCW应用中现有的安全控制方法,提出了在CSCW系统中引入基于X.509证书认证方法的安全控制模型,并设计和实现了一个带证书的安全多媒体会议系统原型MCS/CA。与传统的会议系统相比,MCS/CA增加了证书申请、基于证书的身份认证和通信会话密钥协商以及数据加密传输等安全控制机制。

After an overview of existing security control methods in CSCW systems, the paper proposes a new security control model which introduced the X.509 certificate-based authentication method into CSCW systems. Based on this model, the design and implementation of a secure multimedia conference system prototype, MCS/CA are discussed. In contrast to conventional conference system, MCS/CA enhanced integrated security control mechanism with certificate application, certificate-based authentication, session key negotiation, and data encryption/decryption.
