F&C eID Scenari Innovativi di Identità Digitale


The project aims at studying emerging technologies in digital identity with the goal of implementing a POC in the context of “Enter with CIE” digital identity scheme.

The project is focus on the following research topics:

  • OpenID Connect (OIDC): design and security assessment of the OIDC profile for the CIE id digital identity system, we a focus on federation, cross-domain sharing and session management solutions.
  • Fast IDentity Online (FIDO): study of the state-of-the-art of and design of FIDO solutions for online authentication at Level 2 in federated and non-federated contexts and a solution for unlocking a digital identity wallet supporting the offline scenario.
  • Digital Wallet: design and security analysis of features related to the European Digital Identity Wallet, we focus on trust model, PID/(Q)EAA data model and PID/(Q)EAA issuance flows adopting several features of the “OpenID for Verifiable Credential Issuance”.
  • Face verification: survey on face verification threats and attack patterns that can be used in remote identity proofing and design for the PUK recovery solution.


  • Period: from 01/04/2022 until 31/12/2023.
