Abstract

Due to their nature, Peer-to-Peer (P2P) systems are subject to a wide range of security issues. In this paper, we focus on a specific security property, called the root authenticity (or RA) property of the so-called structured P2P overlays. We propose a P2P architecture that uses Trusted Computing as the security mechanism. We formalize that system using a process algebra (CSP), then verify that it indeed meets the RA property.
