PUCC Architecture, Protocols and Applications

Compared with traditional Internet technologies, peer-to-peer has functions to realize resource discovery, resource sharing, and load balancing in a highly distributed manner. In addition to the Internet, new networks such as home network, ad-hoc network and sensor network are emerging. An easy prediction is the emergence of a new environment in which many sensors, people, and many different kinds of devices coexist, move, and communicate with one another over such heterogeneous networks. Peer-to-peer is one of the most important and suitable technologies for such ubiquitous networking since it supports discovery mechanisms, simple one-to-one communication, free and extensible distribution of resources, and distributed search to handle the enormous number of resources. Peer-to-peer Universal Computing Consortium (PUCC) was established in 2005 to develop a peer-to-peer networking platform for realizing applications in ubiquitous networking environment, which include home appliance applications. This paper presents PUCC architecture, protocols and applications.

Applying XML Signature and XML Encryption to Peer-to-Peer Platform Security

As several general-purpose peer-to-peer platforms have been developing in recent years, it is required that the peer-to-peer platforms should provide reasonable security services to their applications. For the platform security, it is quite important to choose the security mechanisms and protocols (e.g. TLS etc.) as its fundamentals on which the characteristics and performance of the peer-to-peer platform depend. In this paper, we will introduce a study of applying XML Signature and Encryption to the security architecture over the proposed peer-to-peer platform developed by Peer-to-peer Universal Computing Consortium (PUCC).
