AB - This paper proposes DID-ZKP-MFA, a privacy-preserving multi-factor authentication framework integrating decentralized identity and zero-knowledge proofs. The protocol combines DID-based registration, ZKP-based selective disclosure, and dynamic challenge-response. Its security is analyzed using Pedersen commitments, fuzzy extractors, Groth16, and the UC framework. In 100 prototype runs, mobile end-to-end authentication averaged 164.8 ms with 1,428 bytes per session. The design protects credentials and proof transcripts; identifier-level unlinkability additionally requires pairwise DIDs or session-specific pseudonyms.
