bbs_plus

BBS+ signature according to the paper: Anonymous Attestation Using the Strong Diffie Hellman Assumption Revisited. Provides

• signature creation and verification in both groups G1 and G2.
• proof of knowledge of signature and corresponding messages in group G1 as that is more efficient.

Modules

1. Signature parameters and key generation module - setup
2. Signature module - signature
3. Proof of knowledge of signature module - proof

The implementation tries to use the same variable names as the paper and thus violate Rust's naming conventions at places.
