Fully distributed authentication with locality exploitation for the CoDiP2P peer-to-peer computing platform
MetadataShow full item record
CodiP2P is a distributed platform for computation based on the peer-topeer paradigm. This article presents a novel distributed authentication method that suits the platform and adapts to its characteristics. The developed method is based on the Web of Trust paradigm, i.e., not depending on a traditional
PKI infrastructure, and focuses on efficiency both in the number of messages transmitted and digital signatures processed by exploiting the inherent locality found in the platform. As part of the method, a reliable and efficient distributed public key repository is developed taking CoDiP2P’s de Bruijn topology as a cornerstone.
