DIDComm gets formal

Input | Output takes the setting of solid work foundations very seriously. A recent example of this is the research on Decentralized Identifier Communication (DIDComm) through the paper ‘What did come out of it? Analysis and improvements of DIDComm messaging.' which is being presented at this week’s CCS’24, ACM’s flagship conference for computer and communications security. The…

Universal Anonymous Signatures: bridging past, present, and future of anonymous authentication

Recently, we got the paper 'Foundations of Anonymous Signatures: Formal Definitions, Simplified Requirements, and a Construction Based on General Assumptions' accepted into FC'24 – the 2024 edition of the Financial Cryptography conference. This paper presents Universal Anonymous Signatures (UAS).

We are really excited about it as, besides bridging several subfields in the domain of anonymous authentication, UAS sets the path towards what we believe could be (part of) the future of Self-Sovereign Identity and something we will definitely push for integration within the Atala
