Improbable differential cryptanalysis [PDF]
Proceedings of the 6th International Conference on Security of Information and Networks, 2013 Statistical attacks on block ciphers make use of a property of the cipher so that an event occurs with different probabilities depending on whether or not the correct key is used. For instance, differential cryptanalysis [3] and truncated differential cryptanalysis [5] consider characteristics or differentials which show that a particular output ...

Improved conditional differential cryptanalysis [PDF]
Security and Communication Networks, 2014 AbstractIn lightweight cryptographic primitives, non‐linear feedback shift registers (NFSR) are widely used nowadays. At ASIACRYPT 2010, conditional differential cryptanalysis was proposed to analyze NFSR‐based cryptosystems. To get better result, we propose an improved version of this attack.

Cryptanalysis of an MPEG-Video Encryption Scheme Based on Secret Huffman Tables [PDF]
, 2007 This paper studies the security of a recently-proposed MPEG-video encryption scheme based on secret Huffman tables. Our cryptanalysis shows that: 1) the key space of the encryption scheme is not sufficiently large against divide-and-conquer (DAC) attack ...

Boosting Differential-Linear Cryptanalysis of ChaCha7 with MILP
IACR Transactions on Symmetric Cryptology, 2023 In this paper, we present an improved differential-linear cryptanalysis of the ChaCha stream cipher. Our main contributions are new differential-linear distinguishers that we were able to build thanks to the following improvements: a) we considered a ...

Improvement of the Minimal‐Guess‐Basis MILP Model and Its Application to ESF
IET Information Security, Volume 2026, Issue 1, 2026.The guess‐and‐determine technique find wide applications in the recovery of unknown variables within given system of relations. The fundamental concept behind this technique involves guessing certain unknown variables and deducing the remaining ones based on the relational system.
