Incorrect naming of the signature scheme used #249

Hi there,

I am writing a paper describing an anonymous credential scheme that works with BBS+ signatures. Basically, I am migrate the DDA+ protocol from Camenisch, J., Drijvers, M., Lehmann, A. (2016). Anonymous Attestation Using the Strong Diffie Hellman Assumption Revisited on Anonymous Credentials. I plan to refer to the specification https://identity.foundation/bbs-signature/draft-irtf-cfrg-bbs-signatures.html. I noticed that you refer to BBS signatures in the specification, although you specify BBS+ signatures. Would it be possible to change the name from the BBS signature scheme to the BBS+ signature scheme and thus adjust other parts of the specification such as the introduction?

Best regards Chris

Hi @MrM0nkey, this question was raised and discussed by the WG early days, see #30. We elected to drop the + mainly for very practical reasons and don't plan to re-introduce it. Further clarification in the introduction may be added to make this association/decision more obvious.

Discussed on WG call 6th of Mar. Agreement is that for various practical reasons the WG call will not consider updating the name. See #30. Closing.

Hi @tplooker and @BasileiosKal, thanks for your quick response. I would definitely recommend that you be more explicit in the introduction about BBS+ and why you decided to omit the +. At the moment, your reference to BBS "The name BBS is derived from the authors of the original academic work of Dan Boneh, Xavier Boyen and Hovav Shacham where the scheme was first described" is certainly misleading to uninformed readers.

Best regards Chris
