Region division and trust management mechanism-based security level routing method and application

Abstract

The invention discloses a region division and trust management mechanism-based security level routing method and application. The method comprises the steps of network model building, node trust management, cluster head selection, routing building and routing. In the method, the idea of region division and a credit management mechanism are employed in stages of cluster head selection and intra-cluster and inter-cluster routing building of a routing algorithm, so as to isolate malicious nodes rapidly and accurately and make cluster distribution fit with the indoor structure. The method not only balances network energy consumption but also ensures various kinks of data to be transmitted safely and effectively. When the routing method provided in the invention is applied to the intelligent home appliances, the network energy consumption is balanced, further, various kinds of data is ensured to be transmitted safely and effectively in the intelligent home appliance scene.

Description

technical field [0001] The invention relates to a routing method and its application, in particular to a security level routing method and application based on area division and trust management mechanism. Background technique [0002] In the smart home scenario, the data perceived by nodes is mostly environmental, physiological, and behavioral data. This data involves personal privacy and personal life safety. There are many potential safety hazards, so that the possibility of nodes undertaking data transmission tasks being attacked is greatly increased, especially for A class of internal attacks launched by captured nodes that have mastered the key information and obtained identity recognition are extremely weak. On the other hand, the obvious pattern distribution of smart homes and the regional diversity of collected data make them different from traditional smart systems. In view of the obvious structure and weak resistance to internal attacks in smart home scenarios, t...

Although its trust value will decrease with the implementation of malicious behavior, malicious nodes will keep their trust value above the threshold and remain hidden in the network

Therefore, the traditional reputation mechanism has a blind spot for identifying such betrayal nodes. The most important thing is that this kind of betrayal attack is an adjustable means to describe the trust value of a node, which means that the betrayal attack can be launched in combination with factors such as packet loss and behavior evaluation. Betrayal attacks with different attributes, so once the routing algorithm integrates the traditional reputation mechanism, its network performance will be greatly weakened
