一种移动Ad Hoc网络灰洞攻击检测机制

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

Jaydip Sen, M. Girish Chandra, Harihara S. G., Harish Reddy, P. Balamuralidhar

摘要:

保护网络层免受恶意攻击是移动自组网中一个重要且具有挑战性的安全问题。针对移动局域网中AODV路由协议,提出了一种安全机制来抵御协作灰洞攻击。灰洞是在响应于来自源节点的路由请求消息而将自身确认为具有到目的地节点的最短路径之后选择性地丢弃和转发数据分组的节点。所提出的机制不应用任何加密原语的路由消息。相反,它通过检测和响应任何节点的恶意活动来保护网络。仿真结果表明,该方案具有显着的高检测率与适度的网络流量开销。

英文摘要:

Protecting the network layer from malicious attacks is an important and challenging security issue in mobile ad hoc networks (MANETs). In this paper, a security mechanism is proposed to defend against a cooperative gray hole attack on the well known AODV routing protocol in MANETs. A gray hole is a node that selectively drops and forwards data packets after it advertises itself as having the shortest path to the destination node in response to a route request message from a source node. The proposed mechanism does not apply any cryptographic primitives on the routing messages. Instead, it protects the network by detecting and reacting to malicious activities of any node. Simulation results show that the scheme has a significantly high detection rate with moderate network traffic overhead.
