SPoK missing in bbs signature scheme #108
Description
Activity
Hi,
certainly! It should be relatively easy to do using the Schnorr framework.
We have a similar "proof that I know a signature" example for Pointcheval Sanders signatures in the Subzero example list, too, so you can generate a first version of the proof you need using Subzero.I'm quite busy right now, so I won't implement this myself (though it would be a nice addition). But if you want to give it a shot and you run into questions or weird issues, don't hesitate to contact me :)
BBS signature scheme is missing proof of knowledge. It's a vital part of the BBS scheme for it adds selective disclosure feature.
Can the current implementation be extended for SPoK?
