Generates a random secret key and its corresponding public key.
Proves the caller owns the key image for an election, bound to a fresh verifier nonce. The secret key never leaves the device; the proof reveals nothing about it. Sign a vote in step D first to get a matching key image for step G.
Public-input only — anyone can run it. The key image comes from signing a vote (step D) for the same election; the nonce must be the one the prover used.
