摘要: 针对现有无线传感器网络路由协议存在的安全问题,提出了一种改进的Directed Diffusion路由协议。该协议采用对称加密、消息完整性校验码和短签名技术来实现对协议消息分组的保密性、新鲜性和完整性等安全属性,因而能够在存在主动或被动攻击者的情况下,具有对虚假路由信息、Sybil、确认欺骗等常见路由攻击的抵抗能力。通过增强无线传感器网络路由协议Directed Diffusion的安全性,可以有效地节约网络节点的能量,维持网络服务的持续可用性。通过比较和分析,所提的改进的Directed Diffusion协议是一个有效的安全路由协议,能够在仅增加少量通信和计算复杂度的情况下实现安全路由建立过程。

Abstract: Aiming at the security problem of the existing routing protocols in wireless sensor networks,an improved Directed-Diffusion protocol is proposed.In this protocol,some technologies,such as symmetric encryption,message integrity check code,and short signature,are used to implement the security properties of each protocol message packet,such as privacy,fresh,and integrity.Therefore,in this case,the proposed routing protocol can defend main route attacks, such as spoofed routing information,Sybil attack,and acknowledgement spoofing,in despite of the active adversary or the passive adversary.To raise the security level of the Directed-Diffusion routing protocol in wireless sensor networks is quite useful for saving the energy of the network nodes and maintaining the continuous usability.Through comparisons and analyses,the proposed Directed-Diffusion protocol is a comparatively efficient and secure one,which can achieve the secure route establishment at the cost of only a little performance in communication and computation.
