摘要: | 由于ad hoc网路路由协定于设计时欠缺安全性的考量,任何假造窜改的错误路由讯息将扰乱整个路由系统,并使得目前运行于ad hoc网路路由协定遭受到严重的威胁。而目前所提出针对安全路由机制的研究,大多采行密码学中非对称式运算基础运作,也因为非对称式架构运算的高成本,使得这些机制不适用于移动式网路环境下。在本篇论文里,我们将提出一个在路由路径上的合作式攻击模型,并用于鉴别目前所用来保护路由资讯方法之不足点,针对其不足点,我们提出一个有效的路径认证机制,在特定的路由需求路径上,确保路由资讯的完整性,并有助于目前的路由协定对抗路由攻击。 Ad hoc routing protocols are vulnerable due to the absence of security mechanism. Forged routing advertisement can disrupt the routing scheme. Research work has been proposed for securing the routing protocol in ad hoc networks. Some of them deployed the asymmetric cryptographic primitive, which are often infeasible in the mobile environment. In this paper, we discovered a strict, cooperative disruption attack behavior on the route path and identify the deficiency about present secure mechanisms for protecting the routing information. We proposed a path authentication scheme which relies on efficient symmetric cryptographic authentication approach. The Random Assignment Path Authentication (RAPA scheme) guarantees the integrity of a complete request route path in route discovery procedure and help the current on-demand routing protocol for resisting against the routing disruption attacks. Our scheme can be adjusted to meet different efficiency and security requirements for the various applications. |
