具有自我恢复功能的密钥管理方法在MANET网络中应用研究

Research of the Self-healing Key Management in MANET

针对MANET网络动态拓扑和节点处理能力弱等特征,提出了适合MANET网络环境并利用密钥的上下文来恢复网络密钥的密钥管理方法,有效地降低了系统通信量;给出了一个安全有效的密钥分配模型,该模型在占用内存和减少运算复杂性方面都具有非常明显的优势;分析结果表明该方案在安全性方面具有明显优势,分析验证了该算法在MANET网络中使用的有效性和可行性.

A self-healing key management method by using the context of the message according to the dynamic topology and low process ability of MANET is proposed in the paper, which can reduce the system communications overhead;it also offers an efficient key distribution method to reduce the memory and computation overhead compared with the common self-healing key management protocol. ;the paper analyzed the research results verified the secure predominance, efficiency and availability to MANET.
