摘要： 为了解决Ad Hoc网络中的安全性问题,建立一个Ad Hoc环境下的新的组播密钥管理方案,从而更好地解决密钥产生、分发以及动态成员管理问题.采用二级管理模式的簇集架构下的安全组播密钥管理机制,提出了基于EBS方法的组播密钥管理协议,并利用卡诺图方法协助群组通信消息的传送.本密钥管理机制的设计除满足安全性需求外,与其他机制比较,每个节点所存储的密钥数量以及更新群组密钥所需通信代价更少.

Abstract: To solve the security problem in ad hoc network, a new multicast key management scheme in ad hoc environment is given as a better solution to the generation, distribution and management of dynamic members of cipher keys. Introducing the key management mechanism of secure multicast under the cluster framework of two-level management pattern, an EBS-based multicast key management protocol is put forward to assist the transmission of group communication messages by virtue of karnaugh map. Besides meeting the security requirements, the number of keys to be stored in each and every node and the communication costs required for group key updating in the key management mechanism are both much less than those of other mechanisms.
