Optimal Security Proofs for Full Domain Hash, Revisited

RSA Full Domain Hash (RSA-FDH) is a digital signature scheme, secure against chosen message attacks in the random oracle model. The best known security reduction from the RSA assumption is non-tight, i.e., it loses a factor of q s , where q s is the number of signature queries made by the adversary....
