安全多播中一种基于遗传算法的密钥分配机制

摘要

Multicast communication is becoming the basis for a growingnumber of applications. It is therefore critical to provide founded security mechanism for multicast communication. In this paper, the core problem of large-scale secure multicast communication is analyzed and a novel solution to the scalability problem of multicast key management is presented. It is based on the genetic algorithm and can deal with any class of key graphs with frequent joining and leaving members. Experiments proved that it has high efficiency and quality, and is better than the traditional algorithms.%随着多播通信技术的发展，安全问题逐渐成为多播通信的核心问题.本文主要讨论了安全多播通信中密钥管理问题，提出了一种适于处理多播群组成员动态变化的基于遗传算法的密钥分配机制.实验表明，它比传统的密钥管理算法具有较高的效率和可靠性.
