FOX : A New Family of Block Ciphers
In this paper, we describe the design of a new family of block ciphers based on a Lai-Massey scheme, named FOX. The main features of this design, besides a very high security level...

Cryptanalysis of SFLASH with Slightly Modified Parameters
SFLASH is a signature scheme which belongs to a family of multivariate schemes proposed by Patarin et al. in 1998 [9]. The SFLASH scheme itself has been designed in 2001 [8] and ha...

How to Strengthen Pseudo-random Generators by Using Compression
Sequence compression is one of the most promising tools for strengthening pseudo-random generators used in stream ciphers. Indeed, adding compression components can thwart algebrai...

A Formal Approach for Automated Reasoning about Off-Line and Undetectable On-Line Guessing
Abstract. Starting from algebraic properties that enable guessing lowentropy secrets, we formalize guessing rules for symbolic verification. The rules are suited for both off-line ...

A secure variant of the Hill Cipher
The Hill cipher is a classical symmetric encryption algorithm that succumbs to the know-plaintext attack. Although its vulnerability to cryptanalysis has rendered it unusable in p...
