I INTRODUCTION The recent emergence of novel network applications such as Gnutella, Freenet, and Napster has reincarnated the familiar peer-to-peer (P2P) architecture model of the original Internet in new and innovative ways in an effort to facilitate worldwide sharing of information [1]. As a result, there is an ever-increasing need for distributed protocols that would allow peer-to-peer appli...

PEER-TO-PEER (P2P) computing has attracted much attention from both the academic community and industry. This is fueled by the successful deployment and adoption of many domain specific P2P systems. For example, Freenet and Gnutella enable users to share any digital files (e.g., music files, video, images), Napster allows sharing of (mp3) music files, ICQ facilitates exchanges of personal messa...

This paper presents a review of peer-to-peer network security. Popular for sharing of multimedia files, these networks carry risks and vulnerabilities relating to data integrity, spyware, adware, and unwanted files. Further attacks include those of forgery, pollution, repudiation, membership and Eclipse attacks, neighbor selection attacks, Sybil, DoS, and omission attacks. We review some protec...

E-Commerce, Electronic Commerce, is the buying and selling of products and services by businesses and consumers over the internet. Typically there are three types of E-project presents a B2C E-commence application – MP3 online shopping cart. Normally, the music is stored as tracks in the CD-ROM or wave files. The wave file is standard the audio signal format. MP3 standards for MPEG1 layer 3. No...

The paper starts with a description of the fundamental principles of modern Digital Rights Management Systems. This is the basis for the discussion of their most important security aspects from the provider’s view on the one hand and the customer’s view on the other hand. The second half of the paper focuses the new DRM standard from the Open Mobile Alliance (OMA) and its implementation on “ope...

Since its creation in the early seventies, the Internet has adopted a “best-effort” service, which relies on the following three principles: (1) No traffic is denied admission to the network, (2) all traffic is treated in the same manner, and (3) the only guarantee given by the network is that traffic will be transmitted in the best possible manner given the available resources, that is, no art...

Music is from far one of the most important types of media that is being exchanged in today's open networks. Users, pushed by a growing number of factors are exchanging more and more music files using popular P2P sharing technologies, such as Kazaa, e-Mule or Gnutella. If from one side this fact is important and positive, from the other side it is driving to a growth in the number of piracy sit...

Peer-to-Peer (P2P) and Mobile Ad-hoc Networks (MANETs) share similar characteristics in terms of their design goals and the principles of their routing and applications. They also fundamentally address the same problem: How to provide seamless connectivity and services in a dynamic and decentralised environment. Given their parallel objectives, these technologies, if unified, will realise MANET...
