OLSR路由协议中MPR节点安全性研究
Security Study of MPR Nodes in OLSR Routing Protocol
摘要
Abstract
OLSR (optimized link state routing protocol) is a first response routing protocol. The MPR ( Multi-Point Relays) nodes are vulnerable to malicious attacks and the routing protocol will result in serious crash. In response to this security risk,present program of MPR nodes against attacks; technology of message encryption and message frequency detection. Technology of message encryption encrypts HELLO messages which are broadcasted to prevent the attack nodes; Technology of message frequency detection detects the frequency of HELLO messages,and if the frequency is too large,you can charge the HELLO message as a malicious node. Simulation results show that this scheme can effectively resist the attack of the MPR nodes to ensure the safety of OLSR routing protocol.关键词
