OAEP Reconsidered
The OAEP encryption scheme was introduced by Bellare and Rogaway at Eurocrypt ’94. It converts any trapdoor permutation scheme into a public-key encryption scheme. OAEP is widel...

Fully Private Auctions in a Constant Number of Rounds
Abstract. We present a new cryptographic auction protocol that prevents extraction of bid information despite any collusion of participants. This requirement is stronger than commo...

A Machine-Checked Formalization of the Random Oracle Model
Abstract. Most approaches to the formal analysis of cryptography protocols make the perfect cryptographic assumption, which entails for example that there is no way to obtain knowl...

How to Compress Rabin Ciphertexts and Signatures (and More)
Ordinarily, RSA and Rabin ciphertexts and signatures are log N bits, where N is a composite modulus; here, we describe how to “compress” Rabin ciphertexts and signatures (among...

Machine-Checked Security Proofs of Cryptographic Signature Schemes
Abstract. Formal methods have been extensively applied to the certification of cryptographic protocols. However, most of these works make the perfect cryptography assumption, i.e....

On the Generic Insecurity of the Full Domain Hash
The Full-Domain Hash (FDH) signature scheme [3] forms one the most basic usages of random oracles. It works with a family F of trapdoor permutations (TDP), where the signature of m...

Password Based Server Aided Key Exchange
We propose a new password-based 3-party protocol with a formal security proof in the standard model. Under reasonable assumptions we show that our new protocol is more efficient t...

Anonymous Signatures Made Easy
Abstract. At PKC 2006, Yang, Wong, Deng and Wang proposed the notion of anonymous signature schemes where signatures do not reveal the signer’s identity, as long as some parts of...

Security under key-dependent inputs
In this work we re-visit the question of building cryptographic primitives that remain secure even when queried on inputs that depend on the secret key. This was investigated by B...

Hash-and-Sign with Weak Hashing Made Secure
Abstract. Digital signatures are often proven to be secure in the random oracle model while hash functions deviate more and more from this idealization. Liskov proposed to model a ...
