摘　　要：组播安全领域的研究主要集中在端到端的数据保护方面。针对大型组播系统访问控制问题的研究成果不多,已有的研究结果存在很多局限。提出了基于SPKI技术的组播分布式访问控制系统MDAC,和现有的其它方案相比,MDAC不仅具有优越的性能,而且具备分布式、支持非对称组播、授权委托和隐私保护等特性。Current efforts on multicast security mainly focus on end-to-end data protection, but solutions on access control of large multicast system are very few. Even all the existent solutions have many different limitations. Thereinto, the excellent ones are even fewer.An access control system for large multicast system named MDAC is presented. Comparing with other solutions, MDAC has not only excellent performance, but also characteristics of distribution, supporting asymmetrical multicast, delegation and privacy protection.
