Today, I had the great opportunity to present our work on the security of authentication protocols based on Verifiable Credentials at the 2nd Workshop on #Privacy Issues in Distributed Social. Great (and intense) discussion! #KnowledgeGraphs #PIDSKG23

The 2nd session started with a presentation on "Authentication Protocols based on Verifiable Credentials" by Christoph Braun (KIT) in collaboration with Tobias Käfer (KIT) & Ross Horne (University of Luxemburg) #authentication #VerifiableCredentials

@cost_dkg Very concentrated faces there in the discussion 🤔 it was way more fun to present in front of the crowd than it seems 😅

@fluepke Good thing they are not using it in production. Oh...

Thanks for checking it out (:

@fluepke @kgbvax @Fraunhofer_FIT Wenn ihr noch etwas zum Rumspielen sucht, habt ihr euch schon die IRMA app (https https://t.co/mMsU2jbQfK) angeschaut? Die ist wohl in den Niederlanden beliebt...
