WebFeb 29, 2016 · Most generic p-ABC schemes are based on Camenisch-Lysyanskaya (CL) [24,25] or Pointcheval-Sanders (PS) [26] signatures, with the latter gaining importance because of their better efficiency. In ... WebSep 7, 2024 · A second issue is that their underlying base signature schemes, namely Camenisch–Lysyanskaya and Pointcheval-Sanders [41, 42] signatures, are not a priori suitable to a multi-signer setting as needed to distribute issuance. Indeed, with those signature schemes, all signers would have to agree on a common randomness.
