Research On Anonymity Evaluation Of MIX Anonymous Network

In the current field of network communications,anonymous network has been widely popular as an indispensable communication solution.In the research area of anonymous communication technologies,most anonymous communication systems are based on the idea of MIX anonymous network to communicate anonymously.By analyzing and researching the anonymity of MIX anonymous network,it is valuable to evaluate the anonymity of MIX anonymous network for measuring its communication mechanism.Besides,it is helpful to improve the anonymity and system performance of MIX anonymous network.This paper investigates and analyzes the state of the art of anonymity assessment technologies,mainly the development of the technologies and related concepts.Then this paper reviews the related papers in recent years in the field of anonymity evaluation.In this paper,a model of AEBN anonymity assessment is proposed,which can evaluate the anonymity in MIX anonymous communication systems.This model is based on Bayesian network reasoning.In this paper,we introduce the relevant concepts involved in the model,and the construction process of the model is expounded in detail.Simultaneously,we apply the method of exact reasoning and approximate reasoning respectively to the quantification and evaluation of the anonymity of MIX anonymous network.The application of anonymity evaluation under different output strategies in MIX anonymity network is analyzed in detail.This paper also presents a MFBS anonymity assessment method.In this research,firstly,we analyze the path selection algorithm based on bandwidth strategy and the related constraint condition of anonymity.Secondly,we illustrate the overall architecture design and the key module design of the MFBS anonymity assessment method.Meanwhile,the code of the key algorithm module is described.Finally,the application example of the assessment method is presented.According to the running data in the node resource file of anonymous network,the anonymity analysis results under different dimensions can be obtained.By calculating the bandwidth consumed in the running anonymous network,the network environment in which the system is located can be calculated.In this way,we can realize a more comprehensive anonymity evaluation.
