Internet of things trusted routing method based on Core-Selecting and reputation mechanism

Abstract

The invention relates to an Internet of things trusted routing method based on Core-Selecting and a reputation mechanism. The method comprises the following steps that: a source node inquires history interaction record firstly, sends a relay node selection request message to a most trusted node, and broadcasts the relay node selection request message to all neighbor nodes if the most trusted node cannot be found or a selected node does not make feedback; the neighbor nodes assess the confidence level of a request node by a reputation model based on the Core-Selecting after reception of the request message, and provides feedback information indicating whether or not the neighbor nodes wound like to provide relay services; and the source node performs confidence level assessment on the nodes which would like to provide the relay services by the reputation model based on the Core-Selecting after reception of the feedback information, and selects the most trusted relay node finally. Through adoption of the method, the routing security and reliability can be enhanced effectively, and internal collusion attacks can be resisted effectively.

Description

technical field [0001] The invention relates to a trusted route selection method of the Internet of Things based on Core-Selecting and reputation mechanism. Background technique [0002] With the rapid development of the Internet and wireless communication technology, the Internet of Things has emerged as the times require and has become one of the most critical technologies in the new generation of information technology. The Internet of Things is a new type of network that aims to connect various items with the Internet through information sensing equipment and in accordance with agreed protocols for information exchange and communication, so as to realize intelligent identification, positioning, tracking, monitoring and management. It is a network that extends and expands on the basis of the Internet. In recent years, the Internet of Things technology has developed rapidly, and a series of innovative applications and services based on the Internet of Things have also eme...

In addition, the integrity, confidentiality, and privacy of data information in the Internet of Things run through the entire process of data stream transmission, and various routing attacks launched will destroy the integrity and confidentiality of data information, leading to the leakage of private information , therefore, it is particularly important to design a safe and reliable routing protocol

[0004] In recent years, researchers have proposed some Internet of Things security routing protocols, but the existing research results are mainly to modify the existing WMN and WSN security routing protocols, and then apply them to the Internet of Things, without fully considering the system of the Internet of Things The characteristics of the structure and communication methods cannot effectively guarantee the routing security of the Internet of Things; in addition, most of the existing research results are based on the assumption that the nodes in the network are credible, and believe that the nodes are credible after being certified and included in the network. It will not become a malicious node, and cannot effectively resist internal attacks initiated by internal malicious nodes; in addition, although some achievements consider internal attacks, they consider attacks from a single user, and cannot effectively resist alliances or shared networks of multiple internal users. attack, cannot provide good routing security guarantee
