Now-a-days large research groups and alike entities use P2P system for keeping track of research activities and downloading the files. But P2P is in secured as the communication takes place between the end pair of nodes and there is no control or security of the sessions. P2p is a system of acquiring data directly from the clients using a discovery process monitored by the server. As such, in such a system only information about the data and the nodes are maintained at the server and the communication is in peer-to-peer manner between the clients. In a network where data is being changed and new data is released continually, tracking, and managing the repository is a huge task.
