一种移动Ad Hoc网络路由和数据安全方案设计

为了解决移动Ad Hoc网络所面临的路由安全和数据安全问题,基于加密技术,结合路由安全和数据安各自的特点,提出了一种简易、高效、可靠的路由和数据安全解决方案.针对路由安全,合理地采用基于非对称加密的路由测试认证;针对数据安全,采用基于对称加密的数据保护,节省了网络开销,并且在路由认证测试消息中封装对称密的密钥一起发送给解密方目的节点,巧妙利用非对称加密加强了对称加密密钥的安全性,弥补了对称加密的不足,进一步增强了数据安全.两种加密技术各展所长,相辅相成.通过GloMoSim仿真实验表明,该方案具备较高的安全性.

Design of a route and data security solution for moblie Ad Hoc network

In order to protect route security and data security in mobile Ad Hoc network.Based on the eneryption technology,combining with the feature of route security and data security,a simple,efficient and reliable solution for route and data security is designed in this paper.For route security,route autentication based on asymmetric encryption is used reasonably.For data security,symmetric encryption is used reasonably.It reduces network overhead.In addition,the key for symmetric encryption included in the test message for route autentication is sent to the destination node （decrypting peer）at the same time.So the security of the key for symmetric encryption is enhanced by skillfully using asymmetric encryption,making up the shortage of symmetric encryption,enhancing the data security further.The asymmetric encryption and symmetric encryption paly their strengths well and complement each other.The experiment based on Glomosim shows that this solution has good performance.
