Key based routing (KBR) is a lookup method used in conjunction with distributed hash tables (DHTs). While DHTs provide a method to find a host responsible for a certain piece of data, KBR provides a method to find the closest host for that data, according to some defined metric. This may not necessarily be defined as physical distance, but rather the number of network hops. KBR improves the efficiency of decentralized information retrieval in peer-to-peer networks. Distributed hash tables (DHTs) are a class of decentralized distributed systems which partition ownership of a set of keys among participating nodes, and can efficiently route messages to the unique owner of any given key. ... A peer-to-peer (or P2P) computer network is a network that relies on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively few servers. ...
Freenet is a decentralized censorship-resistant peer-to-peer distributed data store. ... GNUnet is a framework for decentralized, peer-to-peer networking. ... Kademlia is an overlay network protocol designed by Petar Maymounkov and David Mazières, for decentralized peer to peer computer networks. ...
In cryptography, a key is a variable value that is applied using an algorithm to a string or block of unencrypted text to produce encrypted text, or to decrypt encrypted text.
Key Distribution is a process that delivers a cryptographic key from the location where it is generated to the locations where it is used in a cryptographic algorithm.
Key Recovery is a process for obtaining the value of a cryptographic key that previously was used to perform some cryptographic operation.
Routing directs forwarding, the passing of logically addressed packets from their source toward their ultimate destination through intermediary nodes (called routers).
Routing differs from bridging in its assumption that address-structures imply the proximity of similar addresses within the network, thus allowing a single routing-table entry to represent the route to a group of addresses.
Routed protocol : Any network protocol that provides enough information in its network layer address to allow a packet to be forwarded from one host to another host based on the addressing scheme, without knowing the entire path from source to destination.
