Implementing Security Solutions for Peer-to-Peer Networks

Given the capricious behavior of P2P networks, we are faced with a new set of problems whose solutions may not always fit the current model used to secure, for example, financial transactions on the internet. In this talk we will first give an overview of the JXTA virtually addressable, P2P network. Next we will discuss a model, Poblano,

which when instantiated on this network, imposes a "security spectrum" yielding degrees of trust as a function of the requirements of the application being secured, the users of that application, and a peer's reputation. Finally, we will show how we implemented Transport Layer Security (rfc2246) using the poblano model.
