Short group signatures

  1. BB and Weak-BB signatures and proof of knowledge of weak-BB signature as described in the paper Short Signatures Without Random Oracles
  2. Proof of knowledge of BB signature adapted from the paper Proof-of-Knowledge of Representation of Committed Value and Its Applications
  3. An optimized implementation of proof of knowledge of weak-BB signature taken from the paper Scalable Revocation Scheme for Anonymous Credentials Based on n-times Unlinkable Proofs. This does not require the prover to do pairings
  4. Similar to weak-BB, proof of knowledge of BB signature that does not require the prover to do pairings.
  5. A keyed-verification protocol for proving knowledge of weak-BB signature. Here the verifier is assumed to have the secret key and the protocol does not require pairings.
