A Universally Composable Scheme for Electronic Cash
We propose a scheme for electronic cash based on symmetric primitives. The scheme is secure in the framework for universal composability assuming the existence of a symmetric CCA2-...

Completion Attacks and Weak Keys of Oleshchuk's Public Key Cryptosystem
This paper revisits a public key cryptosystem which is based on finite string-rewriting systems. We consider a new approach for cryptanalysis of such proposals—the so-called com...

Towards Optimal Double-Length Hash Functions
In this paper we design several double length hash functions and study their security properties in the random oracle model. We design a class of double length hash functions (and ...

Cryptanalysis of the Quadratic Generator
Let p be a prime and let a and c be integers modulo p. The quadratic congruential generator (QCG) is a sequence (vn) of pseudorandom numbers defined by the relation vn+1 ≡ av2 n...

MaTRU: A New NTRU-Based Cryptosystem
Abstract. In this paper, we propose a new variant of the NTRU public key cryptosystem − the MaTRU cryptosystem. MaTRU works under the same general principles as the NTRU cryptosy...

On Highly Nonlinear S-Boxes and Their Inability to Thwart DPA Attacks
Prouff has introduced recently, at FSE 2005, the notion of transparency order of S-boxes. This new characteristic is related to the ability of an S-box, used in a cryptosystem in ...

Short Undeniable Signatures Without Random Oracles: The Missing Link
Abstract. We introduce a new undeniable signature scheme which is existentially unforgeable and anonymous under chosen message attacks in the standard model. The scheme is an embed...

On the Algebraic Immunity of Symmetric Boolean Functions
In this paper, we analyse the algebraic immunity of symmetric Boolean functions. We identify a set of lowest degree annihilators for symmetric functions and propose an efficient al...

Two Algebraic Attacks Against the F-FCSRs Using the IV Mode
This article presents some new results concerning two algebraic attacks against the F-FCSR constructions proposed in [2]. We focus on the parameters of the stream ciphers proposed ...
