Return-Map Cryptanalysis Revisited
As a powerful cryptanalysis tool, the method of return-map attacks can be used to extract secret messages masked by chaos in secure communication schemes. Recently, a simple defen...

Improved Meet-in-the-Middle Cryptanalysis of KTANTAN
We revisit meet-in-the-middle attacks on block ciphers and recent developments in meet-in-the-middle preimage attacks on hash functions. Despite the presence of a secret key in the...

Non-linear Cryptanalysis Revisited: Heuristic Search for Approximations to S-Boxes
Non-linear cryptanalysis is a natural extension to Matsui’s linear cryptanalitic techniques in which linear approximations are replaced by nonlinear expressions. Non-linear appro...

Cryptanalysis of a Video Scrambling Based on Space Filling Curves
In this paper, we study the security of an image scrambling algorithm based on Space-Filling Curves (SFC). A random SFC is a pixel permutation that changes the scanning order with...

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...
