The reflection attack is a recently discovered self similarity analysis which is usually mounted on ciphers with many fixed points. In this paper, we describe two reflection attack...
The previous key recovery attacks against Helix obtain the key with about 288 operations using chosen nonces (reusing nonce) and about 1000 adaptively chosen plaintext words (or 23...
In 2004, a new attack against SHA-1 has been proposed by a team leaded by Wang [15]. The aim of this article5 is to sophisticate and improve Wang’s attack by using algebraic tech...
Abstract. Given (deterministic) ciphers E and E that can encipher messages of l and n bits, respectively, we construct a cipher E∗ = XLS[E, E] that can encipher messages of l + s...
