Sommario
On October 4th, 2023 at 11.30 am Davide Frey (INRIA Rennes) will hold a seminar on "Self Sovereign Identities and Anonymous Credentials" in DEIB Alphs Room (Building 24).
Identity Management Systems (IMS) allow users to prove characteristics about themselves to multiple service providers. These systems evolved from impractical, site-by-site authentication, to versatile, privacy-enhancing Self Sovereign Identity (SSI) Frameworks.
SSI frameworks often use Anonymous Credential schemes to provide user privacy, and more precisely unlinkability between uses of these credentials. However, these schemes imply the disclosure of the identity of the Issuer of a given credential to any service provider. This can lead to information leaks. We offer to deal with this problem by introducing a new Anonymous Credential scheme that allows the user to hide the Issuer of a credential, while being able to convince the service providers they can trust the information provided.
