When implementing SD-JWT verifiable credentials, you must analyze hash collision resistance, claim manipulation, key binding enforcement, and claim name concealment to ensure robust SSI security. Threat modeling helps identify vulnerabilities like hash collisions and key binding weaknesses.

Selective disclosure in SD-JWT protects user privacy by concealing non-disclosed claim names and maintaining user unlinkability. It ensures data protection and confidentiality during transport and storage, preventing unauthorized data correlation.

Key binding enforcement is critical for SD-JWT authentication because it prevents unauthorized presentation of verifiable credentials by binding the token to a specific holder's cryptographic key. This mitigates key binding weaknesses and threat modeling risks.

Yes, it ensures compliance with RFC 9901 and related security best practices for Self-Sovereign Identity (SSI). It reviews SD-JWT designs to enforce key binding, conceal claim names, and protect user data from unauthorized access or correlation.

Limitations of using SD-JWT include potential vulnerabilities to hash collisions, claim manipulation, and data correlation if key binding is not enforced correctly. Proper threat modeling is required to mitigate these SSI privacy and security risks.
