| 摘 要： | 分析了自组网中OLSR(Optimized Link State Routing Protocol)路由协议的脆弱性以及它可能遭受的各种攻击.针对这些潜在的攻击,将公钥机制和信任模型结合,提出了一种防御方案,该方案结合了以反应式PKI为基础进行的公钥签名和信任评价机制,并阐述了如何通过该防御机制有效地防御攻击,最后,用NS仿真工具对该防御机制进行了仿真,并论证了防御方案的可行性.

| Abstract: | This paper analyzes the weakness of the OLSR protocol in the Self Organized Network and introduces some attacks that the protocol may suffer.A corresponding defensive scheme in combination with the reactive PKI and a trust model is presented and the mechanism to resist attacks is introduced.Finally,we use the NS2 to simulate the procedure of the defensive mechanism and discuss the feasibility of the scheme. |
