Problems solved by technology

[0004] However, the above achievements still have the following deficiencies: (1) most of them consider the attack of a single user, and less consider the attack of alliance between two or more users; (2) lack of consideration of internal attack

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] Please refer to figure 1 , the present invention provides a method for routing security and privacy protection in an Internet of Things network, characterized in that it comprises the following steps:

[0035] Step S1: The source node u broadcasts a SETM message to neighbor nodes, and starts the route discovery process;

[0036] Step S2: After receiving the SETM message, any neighbor node v executes the LX-Core mechanism on this node to defend against collusion attacks from other nodes;

[0037] In the LX-Core mechanism, there are the following theorems:

[0038] Theorem 1: In the process of routing selection, when a small number of nodes collude, there will be a relationship WD(N)≥WD′(N), where WD′(N) is when there is collusion WD(N) value at time;

[0039] The stated Theorem 1 is proved as follows:

[0040] Proof: if the system model fig...

Abstract

The invention relates to a method for routing security and privacy protection in an Internet of Things network, comprising the following steps: firstly start the routing establishment process; secondly, conduct credible evaluation on nodes, and record the evaluation results; The Core mechanism defends against node collusion attacks to ensure the safe transmission of data; when there are multiple paths, the best route is selected by combining the node's hop count information and reputation recommendation value information. The present invention can dynamically reflect the behavior of nodes and improve the performance of routing security in the network. At the same time, the dynamic reputation mechanism used in the present invention can meet the requirement of selecting credible routes in the path selection process.

Description

technical field [0001] The invention relates to a method for routing security and privacy protection in an Internet of Things network. Background technique [0002] With the expansion of the application scope of the Internet of Things, more and more private information of users will appear in the network. The disclosure of these private information will bring serious consequences to individuals, society and the country. Therefore, the issue of network and privacy security has attracted widespread attention from users, society and the country, and has become one of the problems that the Internet of Things needs to focus on and solve now and in the future. First, it is the basis for the Internet of Things to further use and provide more network services. As an important part of the Internet of Things, routing protocols are the main target of network attacks. In addition, since the integrity, confidentiality, and privacy of data information in the Internet of Things run throu...
