Relatively-Sound NIZKs and Password-Based Key-Exchange
We define a new notion of relatively-sound non-interactive zeroknowledge (NIZK) proofs, where a private verifier with access to a trapdoor continues to be sound even when the Ad...

Generic Indifferentiability Proofs of Hash Designs
—In this paper, we propose a formal analysis of domain extenders for hash functions in the indifferentiability framework. We define a general model for domain extenders and prov...

Locality-sensitive hashing scheme based on dynamic collision counting
Locality-Sensitive Hashing (LSH) and its variants are wellknown methods for solving the c-approximate NN Search problem in high-dimensional space. Traditionally, several LSH funct...

Secure Two-Party Computation with Low Communication
We propose a 2-party UC-secure protocol that can compute any function securely. The protocol requires only two messages, communication that is poly-logarithmic in the size of the ...

On Authenticated Encryption Using Stream Ciphers Supporting an Initialisation Vector
We describe a systematic framework for using a stream cipher supporting an initialisation vector (IV) to perform various tasks of authentication and authenticated encryption. These...

The Parazoa Family: Generalizing the Sponge Hash Functions
Abstract. Sponge functions were introduced by Bertoni et al. as an alternative to the classical MerkleDamg˚ard design. Many hash function submissions to the SHA-3 competition laun...

Improved zero-sum distinguisher for full round Keccak-f permutation
Keccak is one of the five hash functions selected for the final round of the SHA-3 competition and its inner primitive is a permutation called Keccakf. In this paper, we find t...

Bicliques for Preimages: Attacks on Skein-512 and the SHA-2 family
We introduce a new concept in splice-and-cut attacks on hash functions, which bridges the gap between preimage attacks and a powerful method of differential cryptanalysis. The ne...
