Collaborative Applications Platform Based on Secure P2P Networks

Abstract—The feature of collaborative applications is to utilize various resources distributed over Internet (or intranet). It is a good choice to develop collaborative applications based on Peer-to-Peer (P2P) networks, which can be applied to integrate resources over peers. Most of popular P2P networks focus on files or content sharing and security problems are not seri-ously considered, so they are not good enough for developing collaborative applications. In this paper, secure P2P networks are designed by authentication of joining peers and encrypted data communication. To prohibit misuse of resources, peers are classified into three levels with different priorities. Based on secure P2P networks, a scalable and flexible collaborative application platform composed of core services and user defined services is built. Various resources provided by peers can be easily used by service execution. Two collaborative applications are designed to demonstrate the use of services over peers. It can be expected that more creative collaborative applications will be designed based on the proposed platform. Keywords-Collaborative applications platform; Secure P2P Net-works
