📄️ BBS+
The BBS (Boneh-Boyen-Shacham) Signature Scheme is a cryptographic protocol optimized for efficient, privacy-preserving, multi-message signatures. The scheme is based on pairing-based cryptography, allowing a user to compactly sign multiple messages, with the possibility of verifying each individual message in a set without revealing the actual content. This makes BBS signatures well-suited for privacy-sensitive applications such as anonymous credentials and selective disclosures in identity systems.
📄️ CL03
The CL03 algorithm refers to the one described in the paper, A Signature Scheme with Efficient Protocols by Jan Camenisch and Anna Lysyanskaya.
