摘要
Ad Hoc无线网络是一种自组织移动网络,其中节点是通过不直接连接的中间节点来进行传输。无线网络是非常敏感的,攻击范围可以是被动的偷听,也可以是主动的干预,提供安全支持是一个挑战任务。论文提出了一种分布式密钥安全管理方法,这个方法是选择利他节点,并通过邻居观察完成(k,n)门限密钥,形成强密钥保护避免选择功利性强的节点。本方法对非信任的Ad Hoc网络是十分有效的,避免了k-1对手通过密钥获得信息。
An Ad Hoc wireless network is an autonomous self-organizing system of mobile nodes connected by wireless links where un- directly connected nodes can communicate via intermediate nodes. Providing security support is a challenging task because wireless networks are susceptible to be attacked ranging from passive eavesdropping to active interference. In this paper, a private key distribution management method is presented for wireless Ad Hoc network. The protocol is based on selecting altruism nodes and avoiding utilitarianism nodes by neighbor＇s observation to performed （k,n） threshold cryptography for the strong private key protection. The protocol is efficient for an un- trustworthy Ad Hoe network, also prevents a k-1 adversaries from gaining information about the secret private key.
