Double check ECQV #4
We include an implicit certificate scheme similar to ECQV implicit certificates, as described in "Standards for efficient cryptography, SEC 4: Elliptic Curve Qu-Vanstone Implicit Certificate Scheme (ECQV)".
We also hash the issuer's public key when creating the challenge
I'll read through the security proof somewhat closer eventually. See:
