Abstract: Mobile Ad Hoc network is a special peer-to-peer network that is infrastructure-less，self-organizing and dynamically reconfiguration and mobile.And now people pay more attention to the using of Ad Hoc network in emergence area such as battlefield and disaster rescue.Analyze mobile node authentication method in mobile Ad Hoc networks.The proposed authentication scheme based on signcryption could be used to realize efficient and secure authentication in distributed mobility environment.

摘要： 移动自组网是一种有特殊用途的对等式网络，具有无中心、自组织、可快速展开、可移动等特点，这些特点使得它在战场、救灾等特殊场合的应用日渐受到人们的重视。对移动自组织网络节点间的认证技术进行了研究。分析了目前移动自组网络中适用的认证协议和方法，提出一种基于签密的无线Ad Hoc网络身份认证方案。通过分析证明，该方案在无线Ad Hoc网络环境中有较高的安全性。
