Research In Motion
In the internet today, computing and communications environments are significantly more complex and chaotic than the classical distributed systems, lacking any centralized organization or hierarchical control. This has given rise to the emerging field of Peer-To-Peer (P2P) network as well as the hybrid P2P. In this paper, the author have focused much on the hybrid P2P network, were a central server exists to perform certain administrative functions to facilitate P2P services. Security is an inevitable issue to be considered in the hybrid P2P systems.
