Ad hoc network security routing method based on trust model

Abstract

The invention provides an Ad hoc network security routing method based on the trust model and relates to the technical field of communication. The method comprises the steps of defining trust, obtaining properties involved with the trust, and quantizing and evaluating the properties; acquiring overall credibility of nodes comprehensively, wherein the overall credibility is the composition of the quantized properties; monitoring the state and the behavior of each node in a network, recording the state and the behavior in the network, and providing information of the nodes and the network; monitoring the current state of a neighbor node and judging whether the node is capable of participating in the routing; acquiring, calculating and updating trust values of the nodes; providing the message format, the routing strategy and the routing process inside a routing protocol; analyzing and verifying the security and performance of the routing. According to the Ad hoc network security routing method based on the trust model, energy consumption of the nodes in the network is effectively reduced, network performance is improved, security attack in the network can be resisted, and safe operation of the network routing protocol is guaranteed.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a trust mechanism-based Ad hoc network security routing method. Background technique [0002] The Ad hoc network is composed of a group of wireless mobile nodes. Each node in the network has the functions of a host and a router at the same time. It can not only complete its own communication but also forward information for other nodes, so it is not only widely used in military It also plays a big role in daily life, such as building communication networks in areas with harsh conditions and complex geographical locations. The mobile ad hoc network has the characteristics of self-organization, dynamicity, multi-hop, wireless, distribution, terminal limitation, and security vulnerability. In practice, the network still faces many challenges and problems, mainly including limited energy, communication bandwidth, network security, and network scalability and recoverability. A...

AI Technical Summary

Problems solved by technology

Potential insecurity exists in an open and shared environment, which makes mobile Ad hoc networks more vulnerable to malicious attacks such as eavesdropping and counterfeiting than traditional wired networks

At the same time, because the nodes in the network are in dynamic changes and the network topology is constantly changing, the original security protection scheme for static networks is no longer applicable.

[0004] (2) Resource issues

Due to the existence of various potential security threats and loopholes in the design of routing protocols, routing protocols are extremely vulnerable to sabotage attacks by malicious nodes.
