Abstract: Mobile Ad hoc network is a new kind of wireless mobile self-organization network. Its key management is quite different from that in traditional networks. Based on the properties of the key management in Ad Hoc network, it analyzes the used mechanism and proposes a new key management scheme——YWCR, which is effective and more suited to Ad Hoc network. Experimental results show that the strategy is effective.

Key words: Ad Hoc network, key management, YWCR strategy

摘要： 作为一种无线移动自组织网络，移动Ad Hoc网的密钥管理与传统网络有很大差异，该文分析Ad Hoc网络密钥管理的特点，结合常用密钥管理机制，提出一种新型的密钥管理策略——YWCR，保证密钥管理的有效性，适用于Ad Hoc网络。实验结果证明了该策略的有效性。
