基于对称矩阵的Ad Hoc网络密钥管理方案研究

Ad Hoc网络由于缺乏固定的基础设施,网络安全构成了一个重大的挑战.针对Ad Hoc网络现有的完全分布式证书认证方案做出一个改进.在改进方案中,采用概率统计方法分析了证书创建的难易与方案所提供的安全性之间的关系,针对不同的应用环境,设计了一个安全等级,且每个安全等级对应一个具体的配置参数,应用者可以根据需要进行选择.再用动态规划方法,设计出一种方案,最优地选择到y个节点重建密钥,提高了网络的安全性.

BAC Network Research of Key Management in Ad Hoc Based on the Symmetric Matrix

Because of the lack of fixed infrastructure,Ad Hoc network security is a major challenge.In this paper,Ad Hoc network is a fully distributed certificate of the existing certificating program to do an improvement program to improve the use of statistical methods the probability of a clear analysis of the certificate program created by the ease and security provided by the relationship between for different application environments,the design of a safe level,and each level of security corresponding to a specific configuration parameters,the application can select as needed.Use dynamic programming methods,design a program to select the optimal nodes in the reconstruction of key,improve network security.
