基于Ad Hoc网络的安全路由技术的研究

Study for Secure Routing Technology based on Ad Hoc Network

为防止Ad Hoc网络路由消息的伪造和篡改问题,本文提出了一种安全有效的路由方案SERS(Secure and Efficient Routing Scheme).在DSR(动态源路由协议)中引入了安全机制,在尽可能降低网络资源消耗的基础上,采用SUCV(statistically unique and cryptographically verifiable)标识符避免密钥分发问题,并运用公钥PK与IP地址的绑定来完成密钥分发过程,使用公钥PK与IP地址的绑定来完成密钥分发过程,使得没有密钥的节点不可能伪造报文.使用基于端到端的认证和基于对称密钥的认证检测出被篡改后的报文,从而保证路由消息的不可伪造、并防止其它节点对消息的篡改.实验结果表明,采用该方案能够满足设计的要求.

In order to prevent Ad Hoc network routing information from forgery and tampering,this paper presents a kind of safe and effective routing scheme SERS.In the DSR（Dynamic Source Routing Protocol）,security mechanisms are introduced into it on the basis of reducing network resource consumption as low as possible,and employ SUCV（statistically unique and cryptographically verifiable） [1] identifier to avoid the key distribution problem,bound public key PK and IP address to complete the key distribution process,so nodes without keys can not forge packets.Using end-to-end authentication and symmetric key authentication detect tampered packets,which ensure routing messages not to be forged no false,and prevent other nodes to tamper the messages.The experiment results show that the scheme can meet the design requirements.
