Secure and efficient communication among a set of mobile nodes is one of the most important aspect in P2P wireless networks. Security of various group-oriented applications requires a group secret shared between all participants. Several group key protocols have been presented in the literature to enable secrecy of communication among dynamic group of participants. However, most of them suffer ...

In this paper we describe a model or architecture for autonomous and decentralized collaborative applications to support scientific research, collaborative learning projects and in general collaborative work. We first describe the application environment we had in mind: the design of a peer-to-peer collaborative newspaper application in a large network of schools. We have identified a generic c...

P2P worms pose a serious threat to Internet infrastructure and terminal users because of their overwhelming propagation speed. Manual reactions fall behind the fast propagation of P2P worms. Current automatic techniques are still not adequate to be deployed on a large scale for several challenges including low accuracy, low efficiency, etc. In this paper, we bring forward a repair-andpatch appr...
