Related-Key Attacks on the Py-Family of Ciphers and an Approach to Repair the Weaknesses
The stream cipher TPypy has been designed by Biham and Seberry in January 2007 as the strongest member of the Py-family ciphers, after weaknesses in the other members Py, Pypy, Py...

A Framework for Chosen IV Statistical Analysis of Stream Ciphers
Saarinen recently proposed a chosen IV statistical attack, called the d-monomial test, and used it to find weaknesses in several proposed stream ciphers. In this paper we generali...

Solving Discrete Logarithms from Partial Knowledge of the Key
Abstract. For elliptic curve based cryptosystems, the discrete logarithm problem must be hard to solve. But even when this is true from a mathematical point of view, side-channel a...

A Meet-in-the-Middle Collision Attack Against the New FORK-256
We show that a 2112.9 collision attack exists against the FORK-256 Hash Function. The attack is surprisingly simple compared to existing published FORK-256 cryptanalysis work, yet ...

Linearization Attacks Against Syndrome Based Hashes
Abstract. In MyCrypt 2005, Augot, Finiasz, and Sendrier proposed FSB, a family of cryptographic hash functions. The security claim of the FSB hashes is based on a coding theory pro...
