add support for Pointcheval-Sanders #110

Closed mikelodder7 closed 5 months ago

mikelodder7 commented 5 months ago

Add PS (Pointcheval-Sanders) signature description. These are supported in Anoncreds V2.

PS signatures are similar to BBS+ with the following differences:

  1. Simpler curve operations (no inversions)
  2. Single round threshold settings
  3. Smaller signature proof of knowledge
  4. Smaller credential size
  5. Larger public keys (linear in terms of signeable claims)
