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

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.

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

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 !!

Other systems and Projects Projects Sun's JXTA: JXTA technology is a set of open protocols

that allow any connected device on the network ranging fromcell phones and wireless PDAs to PCs and servers to communicate and collaborate in a P2P manner.

Intel's P2P page IBM Advanced Peer-to-Peer Networking(APPN) Cisco: Advanced Peer-to-Peer Networking (APPN) cryptobox: Cryptobos is a security and anonymity layer

which can be interfaced with any application which needs to communicate securely.

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.

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.

MIT Chord aims to build scalable, robust distributed systems using peer-to-peer ideas. 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.

Other systems and Projects NYU Secure Computer Systems Group TARZAN is a peer-to-peer anonymous IP network layer. Kademlia is a novel routing algorithm for peer-to-peer networks based on

the XOR metric. Coral is a peer-to-peer content distribution system. Cornell: CliqueNet is a peer-to-peer, self-organizing, scalable

communication protocol that gaurantees anonymity. Purdue: DPSR - Dynamic Peer-2-Peer Source Routing. UMD: TerraDir - Decentralized Directory Services. P2PRep is an approach to P2P security where servents can keep track, and

share with others, information about the reputation of their peers. Onion Routing is building an Internet-based system that strongly resists

traffic analysis, eavesdropping and other attacks both by outsiders and insiders.

The Circle is a scalable decentralized peer to peer application. At the core of the Circle is a decentralized hash table, or "Chord".
