7. 7 Classification of Current Peer-to- Peer Systems (New Features) RM: Resource Management CR: Censorship Resistance PS: Performance and Scalability SPE: Security, Privacy and Encryption A: Anonymity RA: Reputation and Accountability RT: Resource Trading.

8. 8 CR: Censorship Resistance Create an anonymous, censorship-resistant data store.. All content is encrypted A peer stores a document by encoding it using certain codes and distributing the resulting fragments throughout the community.

9. 9 Classification of Current Peer-to- Peer Systems (New Features Cont) Anonymity. Peer-to-peer based infrastructure systems have been designed with the explicit aim of providing user Reputation Management. In a peer to-peer network, there is no central organization to maintain reputation information for users and their behavior. Reputation information is, therefore, hosted in the various network nodes. In order for such reputation information to be kept secure, up-to-date, and available throughout the network, complex reputation management infrastructures

10. 10 RT: Resource Trading One application of data trading is digital archiving, where sites protect their collections from failures By distributing multiple copies at remote sites. When a site has a digital collection it wishes to replicate, the site contacts a remote site and proposes a trade. Agreement : I store your data if you store mine !! Peer-to-peer resource trading in a reliable distributed system

15. 15 Other systems and Projects IRIS: Infrastructure for Resilient Internet Systems - is developing a novel decentralized infrastructure, based on distributed hash tables (DHTs), that will enable a new generation of large-scale distributed applications. IRIS GNUnet is a framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. A first service implemented on top of the networking layer allows anonymous censorship-resistant file-sharing. GNUnet MIT Chord aims to build scalable, robust distributed systems using peer-to-peer ideas. Chord Resilient Overlay Networks(RON) Free Haven Project aims to deploy a sytem for distributed, anonymous, persistent data storage which is robust against attempts by powerful adversaries to find and destroy any stored data.

TARZAN Kademlia is a novel routing algorithm for peer-to-peer networks based on the XOR metric. Kademlia Coral is a peer-to-peer content distribution system. Coral Cornell: CliqueNet is a peer-to-peer, self-organizing, scalable communication protocol that gaurantees anonymity.CliqueNet Purdue: DPSR - Dynamic Peer-2-Peer Source Routing.DPSR UMD: TerraDir - Decentralized Directory Services.TerraDir P2PRep is an approach to P2P security where servents can keep track, and share with others, information about the reputation of their peers. P2PRep Onion Routing is building an Internet-based system that strongly resists traffic analysis, eavesdropping and other attacks both by outsiders and insiders. Onion Routing The Circle is a scalable decentralized peer to peer application. At the core of the Circle is a decentralized hash table, or "Chord". The Circle
