移动Ad Hoc网络中合作黑洞攻击的检测机制

A Mechanism for Detection of Cooperative Black Hole Attack in Mobile Ad Hoc Networks

Jaydip Sen, Sripad Koilakonda, Arijit Ukil

摘要:

移动自组织网络(MANET)是自治节点的集合,它们通过形成多跳无线电网络并以分散的方式维护连接来相互通信。由于这些网络具有开放介质、动态变化的拓扑结构、依赖于协作算法、缺乏集中监控点以及缺乏明确的防线等特点,安全性仍然是其面临的主要挑战。因此,大多数用于MANNETWORK的路由协议容易受到各种类型的攻击。按需距离矢量路由(AODV)是一种非常流行的路由算法。然而,它容易受到众所周知的黑洞攻击,其中恶意节点在路由发现过程中错误地伪造到目的地节点的良好路径。当一组恶意节点相互协作时,这种攻击变得更加严重。针对移动自组网中多个黑洞节点的协同攻击,提出了一种防御机制。对该方案进行的仿真结果表明,该机制在检测攻击的同时保持合理的网络吞吐量水平的有效性。

英文摘要:

A mobile ad hoc network (MANET) is a collection of autonomous nodes that communicate with each other by forming a multi-hop radio network and maintaining connections in a decentralized manner. Security remains a major challenge for these networks due to their features of open medium, dynamically changing topologies, reliance on cooperative algorithms,absence of centralized monitoring points, and lack of clear lines of defense. Most of the routing protocols for MANETs are thus vulnerable to various types of attacks. Ad hoc on-demand distance vector routing (AODV) is a very popular routing algorithm. However, it is vulnerable to the well-known black hole attack, where a malicious node falsely advertises good paths to a destination node during the route discovery process. This attack becomes more sever when a group of malicious nodes cooperate each other. In this paper, a defense mechanism is presented against a coordinated attack by multiple black hole nodes in a MANET. The simulation carried out on the proposed scheme has produced results that demonstrate the effectiveness of the mechanism in detection of the attack while maintaining a reasonable level of throughput in the network.
