摘要
针对无线传感器网络中现有部分路由协议考虑安全需求不够的问题,提出一种基于路由协议的安全机制(RPSS)。该安全机制把节省节点能耗和增强路由安全性作为设计目标,采用低能量密钥管理方案和减少转发节点计算量的方法,有效地降低节点的耗能。通过预设密钥和证书,在路由建立阶段增加安全机制,得到一种较优的安全路由方案。经过安全性分析和性能分析,该安全机制可防御虚假路由信息、Sybile和确认欺骗等攻击;还具有适用面广、耗能低和计算量小的优势。
To the problems of less consideration of security requirements on part of existed routing protocols in wireless sensor network, this paper presents a security strategy based on routing protocol. The strategy takes saving of node energy consuming and improving of routing security as its design targets. With methods of applying low-energy key management and reducing transmit-node calculation, energy consummation of each node is effectively reduced. Through the pre-distribution of key and certificate, a security strategy is added to the routing found process and an optimal security routing scheme is obtained. With the analysis on security and function, this strategy can be used to defend spoofed routing information, the Sybil attack, and acknowledgement spoofing, etc. It also contains advantages of widely adaptive, low energy consuming and minimal calculation.
