【摘要】 鉴于简单公钥基础设施技术在授权方面所具备的优点,提出了基于简单公钥基础设施技术的组播分布式访问控制系统,设计了组播分布式访问控制系统鉴别和授权协议,并进行了模拟仿真实验及性能评价。与其他方案相比,组播分布式访问控制系统具备分布式、支持非对称组播、授权委托和隐私保护、边缘路由器计算开销小等特性。更多还原

【Abstract】 As SPKI technology has advantage on the aspect of authorization, this paper presents an access control system for large multicast system named MDAC based on SPKI and MDAC authentication and authorization protocol was also designed. Experiment of simulation and performance evaluation was also done. Compared with other solutions, MDAC has not only excellent performance, but also characteristics of distribution, supporting asymmetrical multicast, delegation and privacy protection, less computing cost in border router.更多还原
