Abstract. AES is the most widely used block cipher today, and its security is one of the most important issues in cryptanalysis. After 13 years of analysis, related-key attacks wer...

We design cryptographic protocols that recognize best case (optimistic) situations and exploit them. As a case study, we present a new concurrent zeroknowledge protocol that is exp...

We study security amplification for weak bit-commitment schemes and improve the efficiency of (black-box) transformations in both the information-theoretic and computational setti...

Abstract. In this paper we combine a recent rotational cryptanalysis with the rebound attack, which results in the best cryptanalysis of Skein, a candidate for the SHA-3 competitio...

Abstract. We describe two improvements to Gentry's fully homomorphic scheme based on ideal lattices and its analysis: we provide a more aggressive analysis of one of the hardn...
