A Security Layer for JXTA Core Protocols

JXTA defines a set of six core protocols specifically suited for ad hoc, pervasive, multi-hop, peer-to-peer (P2P) computing. These protocols allow peers to cooperate and form autonomous peer groups. This paper presents a method that provides security services to the core protocols: privacy, authenticity, integrity and non-repudiation. The presented mechanisms are fully distributed and based on a pure peer-to-peer model, not requiring the arbitration of a trusted third party or a previously established trust relationship between peers, which is one of the main challenges under this kind of environments.
