Multi-verifier signatures generalize traditional digital signatures to a secret-key setting. Just like digital signatures, these signatures are both transferable and secure under arbitrary (unbounded) adaptive chosen-message attacks. In contrast to digital signature schemes, however, we exhibit practical constructions of multi-verifier signature schemes that are provably secure and are based only on pseudorandom functions in the plain model without any random oracles.
