无线传感器网络路由的安全性问题分析

Analysis on Security Problems of Routing Protocols in Wireless Sensor Networks

网络层路由遭受的攻击可归为:哄骗、篡改或重放路由信息、选择性转发、Sinkhole攻击、Sybil攻击、Wormholes攻击、Flooding攻击、应答欺骗。从效果上看,一种是直接对数据进行攻击,另一种是对路由拓扑结构的攻击。针对各种攻击,提出了外/内部攻击的对策。

Most network layer routing against sensor networks fall into one of the following categories： spoofed, altered or replayed routing information, selective forwarding, Sinkholes attacks, Sybil attacks, Wormholes attack, Flooding attacks, and acknowledgements spoofing. These attacks aim at two aspects, on one hand they try to manipulate user data directly; on the other hand they try to affect the underlying routing topology. Countermeasures against these attacks are presented： outsiders and insiders, all sorts of secure routing protocols.
