We put forward a new method of constructing Fiat-Shamir-like signature schemes that yields better "exact security" than the original Fiat-Shamir method. (We also point o...
Abstract. The Full Domain Hash (FDH) scheme is a RSA-based signature scheme in which the message is hashed onto the full domain of the RSA function. The FDH scheme is provably secu...
A blind signature scheme is a protocol for obtaining a digital signature from a signer, but the signer can neither learn the messages he/she sign nor the signatures the recipients ...

We present two machine-checked proofs of the existential unforgeability under adaptive chosen-message attacks of the Full Domain Hash signature scheme. These proofs formalize the ...
Abstract. Canetti and Rabin recently proposed a universally composable ideal functionality FSIG for digital signatures. We show that this functionality cannot be securely realized ...
