摘要
针对无线传感器网络中部分路由协议在设计时对安全性考虑不够的问题,本文提出一种安全高效的路由协议-STEEN协议。该协议是在TEEN(Threshold sensitive Energy Efficient sensor Network protocol)路由协议的基础上,以增强路由安全性同时兼顾网络的能量消耗为目标而设计的。该协议通过预置密钥和采用随机密钥对密钥管理的方法,解决了节点间的认证和安全通信的问题,增强了网络的安全性。通过安全性分析可以看到,该安全路由协议可防御多种针对网络层的攻击。
A TEEN protocol-based security-efficient protocol STEEN is presented. This protocol addresses the problems of inadequate consideration for security in some of existed routing protocols for wireless sensor networks. The protocol, which takes saving of energy consumption and improving of routing security as its design targets, solves the problems of authentication and secure communication between nodes through pre-distribution of key and the random key pair-wise management. Analysis on security indicates that this protocol can be used to defend many attacks at network layer.
