A security routing method for ad hoc network based on trust mechanism

Abstract

The trust mechanism-based Ad hoc network security routing method provided by the present invention relates to the field of communication technology, including defining trust, obtaining attributes involved in trust, quantifying and evaluating attributes; comprehensively obtaining the total trust value of nodes; The trust value is a synthesis of quantified attribute values; monitor and record the status and behavior of each node in the network, and provide node and network information; monitor the current status of neighboring nodes, and judge whether the node is capable of participating in routing; obtain , Calculate and update the trust value of the node; provide the message format, routing strategy and routing working process inside the routing protocol; analyze and verify the security and performance of the above routing. The invention provides a trust mechanism-based Ad hoc network security routing method, which can effectively reduce the energy consumption of nodes in the network, improve network performance, resist security attacks in the network, and ensure the safe operation of network routing protocols.

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.
