| 摘 要： | 解决多播安全的主要措施是多播密钥管理，包括实时密钥管理和批量密钥管理。该文讨论了实时密钥更新管理中的密钥分发问题，分析了密集模式协议实现方法，并针对密集模式协议，添加了实时密钥更新管理模型，分别对星型结构和树型结构的密钥管理，利用NS仿真软件中的多播协议进行了仿真。结果增强了该协议的安全性。

| Abstract: | The main solution to multicast security is group key management, which includes real time key management and batch key management. This paper mainly discusses the group key distribution in real time group rekeying management, analyzes emphatically the realization of the multicast protocol, especially the PIM-DM protocol, directs at the PIM-DM protocol, and develops a model of real time group rekeying management. The author makes use of multicast protocol in software NS to conduct simulation study on key management of centralized mechanism and decentralized mechanism. As a result, the security of this protocol is enhanced. |
