OLSR(最优链路状态路由协议)是一种先应式路由协议,其MPR(多点中继)节点易受恶意攻击,严重时将导致路由协议崩溃。针对这一安全隐患,提出了一种MPR节点综合抗攻击方案:消息加密和消息频率检测技术。消息加密技术主要是对广播的HELLO消息进行加密,防止攻击节点冒充合法节点;频率检测是对HELLO消息发送频率进行检测,若频率过大则可以认为发送该HELLO消息的节点为恶意节点。仿真结果表明,该综合方案可以有效抵制对MPR节点的攻击,保证OLSR路由协议的安全
- Abstract:
-
OLSR (optimized link state routing protocol ) is a fLrSt 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 resuits show that this scheme can effectively resist the attack of the MPR nodes to ensure the safety of OLSR routing protocol
