A secure composition scheme for home networked appliances in P2P networks

Peer-to-peer networks have been utilised for a variety of purposes, from file-sharing to Voice-over-IP, and a particularly interesting area of recent application is that of Networked Appliances. Network Appliances present an exciting opportunity to provide new functionality to appliances used within home networking environments. However, the security for such devices in distributed networks presents many challenges, and remains a largely unresolved issue due to the lack of centralised control. We propose a novel scheme called the Home Networked Appliances Security Scheme (HNASS) to secure communication among peers utilizing the services of home networked appliances. We will look at how these appliances work together, the impact this has on the security of these appliances over P2P networks, and how we can apply our HNASS solution to perform component composition analysis for improving security. This paper presents extended model of HNASS with the description of functions and analytical study of the proposed scheme.
