Are anonymous credentials (such as IBM Idemix) a type of zero knowledge proofs (ZKP)? if so what type of ZKP are they?

The papers such “Security without identification: transaction systems to make big brother obsolete” don not reference ZKP.

My understanding is they both refer to similar topics.

I would rather call them a type of blind signatures. Since signatures stem from non interactive ZKP you can say that they are related.

  • $\begingroup$ Aren't blind signatures also a sub-category of ZKP since they provide the ability to sign data without viewing the data. $\endgroup$

  • $\begingroup$ I don't think so since in ZKP the zero knowledge part concerns the key not the message. In Blind signatures the signer does not see the message and also provides a ZKP of the key $\endgroup$ Apr 7, 2018 at 19:37
