A certificate-poisoning-resistant protocol for the synchronization of Web of Trust networks.
Doctoral thesis, Universidad Nacional Autónoma de México.
Resumen
A fundamental issue of encrypted network communications is ensuring trust on the identity of the counterpart of a communication.
This is commonly achieved by means of a trust distribution model. The decentralized trust distribution model, termed Web of Trust, has been found to have several weaknesses. One such weakness –certificate poisoning– has brought the main OpenPGP certificate keyserver network to the limits of sustainability.
The present thesis presents a protocol for key certification and synchronization that avoids the nocive effects of certificate poisoning, while retaining compatibility with as much as possible of the preexisting OpenPGP and HKP toolset.
