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?

    $\begingroup$ @Paūlo: it's worming it's self into numerous specifications in the wireless / smart meter space, along with a host of Certicom patented methods such as ECMQV. It's a perfect match for bandwidth and space constrained systems. $\endgroup$

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.
