Are there reference implementations of ECQV implicit certificates? I am interested in exploring ECC implicit certificates, specifically using the ECQV protocol. While the actual implementation would not difficult to perform using building blocks provided by most ECC capable libraries, I really would like to compare my application with a reference implementation.

Does anyone know of a reference implementation of ECQV?
For the sake of moving this question off of the "unanswered" list, the answer seems to be no. I spent time looking as implicit certificates are relevant to a project we are beginning to work on.

SECG, which has the draft standard for ECQV, does have a future project for test implementations of their standardized primitives/protocols.

They have a mailing list, but I have not subscribed. You could ask there.
