On the Exact Security of Full Domain Hash
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...

New Signature Schemes with Coupons and Tight Reduction
Amongst provably secure signature schemes, two distinct classes are of particular interest: the ones with tight reduction (e.g., RSA-PSS), and those which support the use of coupon...

Improving the Exact Security of Digital Signature Schemes
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...

The Power of Proofs-of-Possession: Securing Multiparty Signatures against Rogue-Key Attacks
Abstract. Multiparty signature protocols need protection against roguekey attacks, made possible whenever an adversary can choose its public key(s) arbitrarily. For many schemes, p...

Stronger Security Bounds for OMAC, TMAC, and XCBC
OMAC, TMAC and XCBC are CBC-type MAC schemes which are provably secure for arbitrary message length. In this paper, we present a more tight upper bound on Advmac for each scheme, w...
