Abstract

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 identitiesbut 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 aimthe 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.
