At CRYPTO 2019, Gohr pioneered the use of the neural distinguisher (N D) for differential cryptanalysis, sparking growing interest in this approach. However, a key limitation of N D is its inability to analyze as many rounds as the classical ...

In CRYPTO 2019, Gohr successfully applied deep learning to differential cryptanalysis against the NSA block cipher Speck32/64, achieving higher accuracy than traditional differential distinguishers. Until now, the improvement of neural ...

In this paper, we propose a rectangle-like method called rotational-XOR differential rectangle attack to search for better distinguishers. It is a combination of the rotational-XOR cryptanalysis and differential cryptanalysis in the rectangle-...${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$

In CRYPTO 2019, Gohr shows that well-trained neural networks can perform cryptanalytic distinguishing tasks superior to traditional differential distinguishers. Moreover, applying an unorthodox key guessing strategy, an 11-round key-recovery ...

A systematic approach to the fixed-key analysis of differential probabilities is proposed. It is based on the propagation of ‘quasidifferential trails’, which keep track of probabilistic linear relations on the values satisfying a differential ...

Rotational‐XOR (RX) cryptanalysis is a cryptanalytic method aimed at finding distinguishable statistical properties in Addition‐Rotation‐XOR‐C ciphers, that is, ciphers that can be described only by using modular addition, cyclic rotation, XOR ...

Simon and Simeck are two lightweight block ciphers with a simple round function using only word rotations and a bit-wise AND operation. Previous work has shown a strong clustering effect for differential and linear cryptanalysis, due to the ...

Rotational-XOR cryptanalysis is a cryptanalytic method aimed at finding distinguishable statistical properties in ARX-C ciphers, i.e., ciphers that can be described only by using modular addition, cyclic rotation, XOR, and the injection of ...

Post-quantum cryptography has attracted much attention from worldwide cryptologists. However, most research works are related to public-key cryptosystem due to Shor’s attack on RSA and ECC ciphers. At CRYPTO 2016, Kaplan et al. showed that many ...${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$

We present a general framework for the related-key linear attack that can be applied to iterative block ciphers with linear key schedules. The attack utilizes a newly introduced related-key linear approximation that is obtained directly from a ...

Resistance against differential cryptanalysis is an important design criteria for any modern block cipher and most designs rely on finding some upper bound on probability of single differential characteristics. However, already at EUROCRYPT’91, ...

Modern cars are equipped with hundreds of Electronic Control Units (ECUs) connected in a Controller Area Network (CAN). These ECUs are used to perform driving functionalities like the movements of accelerator, brakes, steering wheel, etc. Car hacking ...

The widespread use of sensitive and constrained applications necessitates lightweight (low-power and low-area) algorithms developed for constrained nano-devices. However, nearly all of such algorithms are optimized for platform-based performance and may ...

In this work, we analyze the resistance of Simon-like ciphers against differential attacks without using computer-aided methods. In this context, we first define the notion of a Simon-like cipher as a generalization of the Simon design. For certain ...

This paper focuses on algebraic attacks on the Simon family of block ciphers. We construct equation systems using multiple plaintext/ciphertext pairs, and show that many variables in the cipher states coming from different plaintexts are linearly ...
