基于信任值的无线传感器网络安全路由

Secure Routing Path Using Trust Values for Wireless Sensor Networks

S. Rajaram, A. Babu Karuppiah, K. Vinoth Kumar

摘要:

传统的基于密码学的安全机制,如认证和授权,不能有效地抵抗内部攻击,如虫洞,sinkhole,选择性转发攻击等,在无线传感器网络中,基于信任的方法被广泛用于对抗内部攻击。它提供了一种定量的方法来评估传感器节点的可信性。一个不可信的节点可能会造成相当大的损害,并对数据的质量和可靠性产生不利影响。因此,分析一个节点的信任级别是非常重要的。在本文中,我们重点介绍了间接信任机制,其中每个节点监视其邻居的转发行为,以检测任何节点的行为自私,不转发它收到的数据包。为此,我们使用了一个基于链路状态路由协议的间接信任,它形成了最短的路由,并通过比较所有计算出的路由信任的值,为网络中存在的每一个路由,找到其中最值得信赖的路由。最后,我们比较了我们的工作与类似的路由协议,并显示了它的优势。

英文摘要:

Traditional cryptography-based security mechanisms such as authentication and authorization are not effective against insider attacks like wormhole, sinkhole, selective forwarding attacks, etc., Trust based approaches have been widely used to counter insider attacks in wireless sensor networks. It provides a quantitative way to evaluate the trustworthiness of sensor nodes. An untrustworthy node can wreak considerable damage and adversely affect the quality and reliability of data. Therefore, analysing the trust level of a node is important. In this paper we focused about indirect trust mechanism, in which each node monitors the forwarding behavior of its neighbors in order to detect any node that behaves selfishly and does not forward the packets it receives. For this, we used a link state routing protocol based indirect trusts which forms the shortest route and finds the best trustworthy route among them by comparing the values of all the calculated route trusts as for each route present in the network. And finally, we compare our work with similar routing protocols and show its advantages over them.
