PrivacyPass has two separate issuance protocols. One uses blind RSA signatures, which are more or less an exact mapping to the protocol we described above. The second one replaces the signature with a special kind of MAC scheme, which is built from an elliptic-curve OPRF scheme. MACs work very similarly to signatures, but require the secret key for verification. Hence, this version of PrivacyPass really only works in cases where the Resource and the Issuer are the same person, or where the Resource is willing to outsource verification of credentials to the Issuer.
