Problems solved by technology

However, user behavior evaluation based on AHP only provides user behavior evaluation at a single moment, ignoring the trust consideration of user historical behavior, making the results one-sided and unable to obtain comprehensive information of user trust evaluation, so the evaluation results lack accuracy and comprehensiveness

Embodiment Construction

[0023] Based on the improved AHP user behavior trust evaluation and decision-making method, the invention uses the AHP principle to add time factors to collect and model the evidence of the user's historical continuous time, constructs the user behavior evidence matrix and weight matrix of the continuous time, and calculates the comprehensive security of the user. The evaluation results make the security evaluation for network users more accurate and comprehensive, thereby effectively ensuring the security and credibility of the network.

[0024] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings.

[0025] A user behavior trust evaluation and decision-making method based on improved AHP, the process of the method is as follows figure 1 As shown, the specific process is:

[0026] Step 201, using a security mon...

Abstract

The invention discloses a user behavior trust evaluation method and system based on the improved AHP. The invention uses the AHP thought to model the user behavior evidence, adds the time factor to calculate the multi-dimensional trust vector of a continuous time, and evaluates whether a security threat is exist in the user behavior or not according to the integrated trust. The user behavior trust evaluation method based on the improved AHP comprises the key steps such as user behavior collection and processing, user behavior evaluation and modeling, user behavior evidence weight matrix construction, the construction of the trust matrix based on the time, the construction of the weight matrix based on the time, and user integrated trust evaluation and decision and the like. The invention can effectively guarantee the security and credibility of the network system.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a user behavior trust evaluation method and system based on improved AHP. Background technique [0002] With the development and wide application of the network, network security has become increasingly prominent. Recently, attack techniques and threat methods for various network architectures have emerged one after another, and the security threats faced by network systems will become more and more serious in the future. According to the statistics of the FBI, 83% of information security incidents are caused by insiders or internal and external collusion, of which 16 % from unauthorized use by internal users, so monitoring and evaluation of user behavior in the internal network is important. [0003] At present, the AHP idea has been used at home and abroad to calculate and evaluate the trust degree of user behavior in the network. For example, the invention patent ap...
