【摘要】 移动Adhoc网是一种开放式、无中心、自组织的无线局域网,它的开放通信信道导致它在认证、路由、通信时的安全性很难得到保证。在本文,一种安全的移动Adhoc通信方案被提出,该方案首先对认证中心实行分布式管理,由多个节点协同颁发CA证书,路由建立时,利用CA证书和公钥加密技术对通信双方的信息的可靠性进行验证,在会话密钥协商时,采用Diffic-Hellman算法实现了密钥的协商与交换。最后使用BAN逻辑对该方案进行安全性分析,分析结果证明该方案具有较高的安全性和有效性。更多还原

【Abstract】 Mobile adhoc networks is an open,no center,self-organize and wireless LAN(Local Area Network) .It is difficult to assure the security of authentication,routing and communication,because of its open communication channel.In this paper,a secure scheme for mobile adhoc communication is proposed.At first,it adoptes a distributed scheme to manage CA center,and CA certificate comes from cooperation of some nodes.When routing building,credit of their information is validated by CA certificate and PKI.As key agreement of session,key agreement and exchange is realized by Diffic-Hellman algorithm.At last,security of Secure Communications Scheme proposed in the paper is analyzed by BAN logic.Results show that the Scheme is more security and validity than others methods.更多还原
