A Proposal for an Improved Distributed Architecture for OpenPGP's Web of Trust

Network users usually need a third party validation to prove that they are who they claim to be. Authentication systems mostly assume the existence of a Trusted Third Party (TTP) in the form of a Certificate Authority (CA) or as an authentication server. However, relying on a TTP implies that users do not directly manage their identities, but delegate this role to a third party. This intrinsic issue can generate trust concerns (e.g., identity theft), as well as privacy concerns towards the third party. The main objective of this research is to present an autonomous and independent solution where users can store their self created credentials without depending on TTPs. To this aim, the use of an TTP autonomous and independent network is needed, where users can manage and assess their identities themselves. In this paper, we propose the framework called Three Blockchains Identity Management with Elliptic Curve Cryptography (3BI-ECC). With our proposed framework, the users' identities are self-generated and validated by their owners. Moreover, it allows the users to customize the information they want to share with third parties.

“…The identity of the user will be created by a mathematical calculation based on ECC over the uniqueness of the user; thus, becoming hard for someone on the Internet to vulnerable or steal it. Using users' uniqueness allows avoiding problems like the ones documented in PGP's WoT [3] where any user could use any name without restriction.…”
