The paper introduces a novel approach to digital identity management by combining ring signatures with decentralised identifiers. It focuses on enhancing security, privacy, and user control over their digital identities through the proposed protocol. The protocol leverages cryptographic techniques to ensure anonymity while verifying user identities securely.
The European Union's transition towards electronic identification (eID) raises concerns about privacy and security in online services. Decentralised Identifiers (DIDs) offer unique identifiers for secure digital identities without the need for central registration authorities. DIDs enable self-sovereign identity systems, empowering individuals with control over their data.
Ring signatures provide signer anonymity by allowing signers to dynamically select public keys from a set. The proposed protocol uses Type-T ring signature construction based on Schnorr identification for anonymous identification. The architecture integrates verifiable credentials stored in holders' wallets linked through RingDIDs, ensuring tamper-proof authentication.
The paper emphasizes the importance of security and privacy in digital identity frameworks, highlighting the role of cryptographic methods like zero-knowledge proofs. By implementing the proposed protocol, users can authenticate themselves anonymously while maintaining data integrity and confidentiality.
