Implementing Security Solutions for Peer-to-Peer Networks
Bill Yeager

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,
http://security.jxta.org/servlets/ProjectHome
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.
