Dual-Path Peer-to-Peer Anonymous Approach

Abstract

there are many approaches proposed to provide anonymous peer-to-peer communications. Data sent via peer-to-peer communications is vulnerable to traffic analysis. Traffic analysis is the process of intercepting and analysing messages in order to compromise information from patterns in communications. An intruder can get information about the content of the data, the requester's and provider's identities. Anonymous approaches are designed with the following three goals: to protect the identity of provider, to protect the identity of requester and to protect the contents of transferred data between them. This article presents a new peer-to-peer approach to achieve anonymity between a requester and a provider in a hybrid peer-to-peer information-sharing environment with trusted servers called supper node so that the provider will not be able to identify the requester and no other peers can identify the two communicating parties with certainty. This article shows that the proposed approaches improved reliability and has more security. This approach, based on onion routing and randomization, protects transferring data against traffic analysis attack. The ultimate goal of this anonymous communications approach is to allow a requester to communicate with a provider in such a manner that nobody can determine the requester’s identity and the content of transferred data.
