基于云模型理论的网络用户行为评判模型研究

Study on Network User Behavior Evaluation Model Based on Cloud Model Theory

由于网络的异构性使得网络中的用户纷繁复杂,而众多的网络用户行为表现方式又多种多样,也直接影响到网络的安全性.本文借鉴已有的研究工作,以复杂的网络环境为研究背景,通过对复杂网络环境中用户行为的研究,引入云模型理论,研究并提出了一个基于云模型理论的网络用户行为评判模型,实现了对网络用户行为定量描述及评判;同时研究结果还体现了网络用户行为的不确定性和评判标准的差异性,这样使网络行为评判结果更加符合客观事实.仿真实验进一步验证了本文研究的网络用户行为评判模型能够对复杂的网络环境中网络用户行为做出合理的评判,为复杂的网络环境中网络行为评判的研究提供了有价值的新思路.

The heterogeneity of network makes the network users very complicated, while the large number of network users＇ behav- iors have a variety of manifestations, but also directly affect the security of the network. This paper reference to the having existed a- chievements of the authors, taking the complex network environment as the researching background, by use of cloud model theory, and through researching the network users＇ behaviors in the complex network environment, we proposed the network user behavior e- valuation model based on cloud model theory. This model implements quantitative description and evaluation of network users＇ behav- iors, but also the researched results reflect the uncertainty of the network user behaviors and the differences of the different behaviors＇ evaluation criteria, which make the objective facts more in line with the network user behaviors evaluation results. The simulation re- suits confirm that this network user behavior evaluation model can make a reasonable evaluation of the network user behavior in the complex network environment. The network user behavior trust evaluation model proposed in this paper may provide a new promising method for research of network user behavior evaluation in complex networks environment.
