Darknet
Encyclopedia
The term darknet refers to any private, distributed P2P filesharing network, where connections are made only between trusted peers (sometimes called "friends") using non-standard protocols and ports. Darknets are distinct from other distributed P2P networks as sharing is anonymous (that is, IP addresses are not publicly shared), and therefore users can communicate with little fear of governmental or corporate interference. For this reason, they are often associated with dissident political communications, as well as various illegal activities. More generally, the term "darknet" can be used to describe all non-commercial sites on the Internet , or to refer to all "underground" web communications and technologies, most commonly those associated with illegal activity or dissent .

 who described the concept as follows:

The idea of the darknet is based upon three assumptions:
  1. Any widely distributed object will be available to a fraction of users in a form that permits copying.
  2. Users will copy objects if it is possible and interesting to do so.
  3. Users are connected by high-bandwidth channels.

The darknet is the distribution network that emerges from the injection of objects according to assumption 1 and the distribution of those objects according to assumptions 2 and 3.


The Microsoft researchers argued that the presence of the darknet was the primary hindrance to the development of workable DRM

and Wired. Recently darknets are often discussed in many fields of network security, largely because users who occupy such areas have gone there for various reasons. Some publish on darknets for fear of political reprisal, while others publish on darknets for criminal gain. One trend that has been suggested is the use of "darknets" to share media files that are copyrighted, will become common place. Recent trends show political pressure from many areas are creating enforcement in the form of censorship.

, are not true darknets since peers will communicate with anyone else on the network. Darknet is also commonly used in a broader sense to describe any network which is non commercial, that offers some level of anonymity and or obscurity. These networks usually make it less cost effective to uncover a users activities. Some of these networks are used for whistle blowers as well as criminals. Many "darknets" require software to be installed to access them. Popular "darknets" include "Tor (routing system), Freenet, and I2P (Mix Network)". Almost all known darknets are decentralized, as a result considered peer to peer. The current version of Freenet, unlike typical darknets, claims to be capable of supporting potentially millions of users using an application of small world theory
