TRUST MANAGEMENT IN P2P SYSTEMS USING SORT MODEL

Abstract

This paper is use to solve the problem of the open nature of Peer to Peer system in a Network. The Main problem in P2P system is that every system is treated equally and possess equal rights to every resource in Network. Here the Security of Data or resources is not stated. Hence the trust problem arises in the Network. This Paper presents the solution to the Problem mentioned above by creating a Trusted Environment among the Peer, present in the Network. The trusted environment is created with the use of Distributed Algorithm which satisfies the trustworthiness of other peer to the peer on which it is calculated on the information available to the current peer, this calculation requires two parameters known as Past Interaction and Recommendations received from others. After applying the SORT the proposed system is able to prevent attacks from different malicious behavior model. In SORT, Every peers calculate its own set of parameters based on trustworthiness in relation of other peers in the Network. The Trust environment is required for the purposes like Communication, File Sharing or Resource Sharing. In this system the Algorithm will separate the trusted peers and the malicious peer from one another and will create a secure Environment
