Research On Resource Releasing Model In Anonymous Communication System

With the widespread use of Internet in people?s daily lives and the popularity of e-commerce applications,security and privacy concerns have become the hot topic of the Internet.Traditional encryption technologies can protect the security of the data transmitted in the network,but it can not resist some attacks such as trafic analysis,which leads to the disclosure of user identity information in the communication.Anonymous communication can hide the communication relation between both paties by some way,so that no eavesdropper can infer directly the communication relation or the identity of any paty,procecting the privacy of users in the network.Currently anonymous communication has become the focus in the fields of communication and network security.How to distribute resources among the users is a key issue in the design of anonymous communication system.Elaborate resource publishing model can help anonymous communication system become more anonymous and more efficient.In this paper,we focus on resource publishing model in the anonymous communication system and study some issues about releasing resource.In the general,the following three tasks are completed in this paper:1.In this chapter,we introduce the resource types in anonymous communication system.With the typical anonymous communication system ?Tor?,we describe the importance of the access nodes for resisting blocking.And a structure about resource–releasing is proposed,which is described from resource management,resource distribution channels,resource distribution strategies.we also explain the threats existing in the proposed structure.2.we propose a new resource releasing model cu in which resource is managed centralizedly and distributed randomly among users.To analyse the capacity of this model in defending the harvest attack, we apply Markov model to derive the relation between the probability of obtaining the whole resource and the number of resource requests and valiate our analysis in the experiment.3. With the development of SNS social network, social network's role in the release of resources highlights gradually.With the help of disease transmission model and the characteristics of resource releasing in the anonymous communication system,we establish a new resource releasing model based social network.In the experiment we simulate the the resource propagation in the social network constructed with ?small-world? model,providing a theoretical guidance in the design of resource distribution system based social network and control resource propagation in the social network.
