Embodiment Construction

[0042] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0043] A trust evaluation method for electric power 5G wireless private network communication terminals based on information entropy, comprising the following steps:

[0044] Step 1, for such as figure 1 The terminal communication system of the electric power 5G private network shown in the figure collects the data that the communication terminal communicates with the base station uplink, and the data that communicates with the concentrator downlink, and establishes a trust model for the electric power 5G private network communication terminal;

[0045] The concrete steps of described step 1 include:

[0046] (1) When communicating between terminals, there will only be two cases of successful communication and unsuccessful communication. Therefore, the binomial distribution is used here to simulate the communication between terminals. The termina...

Abstract

The invention relates to an information entropy-based electric power 5G wireless private network communication terminal trust evaluation method, which comprises the following steps of: 1, collecting data of communication between an uplink of a communication terminal and a base station and data of communication between a downlink of the communication terminal and a concentrator, and establishing an electric power 5G private network communication terminal trust model; and step 2, through the electric power 5G private network communication terminal trust model established in the step 1, obtaining an expression of terminal credibility and trust degree based on binomial distribution, and then establishing a trust and credibility evaluation system model to realize trust evaluation. The method can adapt to complex network environments under various attacks and carry out normal evaluation work, and a more accurate trust evaluation result of the terminal equipment can be obtained.

Description

technical field [0001] The invention belongs to the technical field of communication terminal trust evaluation, and relates to a trust evaluation method for electric power 5G wireless private network communication terminals, especially a trust evaluation method for electric power 5G wireless private network communication terminals based on information entropy. Background technique [0002] In the electric power 5G private network, 5G communication, through its technical characteristics such as high speed, high capacity, high reliability, low delay, and low energy consumption, will be used in five aspects: interconnection of everything, precise control, massive measurement, broadband communication, and efficient computing. With a wide range of applications, 5G communication can coordinate wide-area resources in the power system and is an important part of the power Internet of Things. There are a large number of terminal devices in the 5G private network of electric power. Th...
