2024年2月19日 · In this paper, we shift our attention to deep learning-based distinguishers for rotational XOR (RX) cryptanalysis on AND-RX ciphers, an area that has received comparatively less attention. Our contributions include a detailed analysis of the state-of-the-art deep learning techniques for RX cryptanalysis and their applicability to AND-RX ciphers ...

2025年2月5日 · In this paper, a security evaluation framework for ARX ciphers, using modular addition as non-linear component, against rotational-XOR differential cryptanalysis is proposed. We first model all the possible propagations for rotational-XOR difference and rotational-XOR differential probability by some conjunctive normal form clauses.

Abstract: In this paper, a security evaluation framework for AND-RX ciphers against rotational-XOR differential cryptanalysis is proposed. This framework first models the structure of all the possible rotational-XOR differential (abbreviated to “RXD”) trails and introduces a method to calculate this structure round by round.

2022年12月14日 · A natural extension of the differential-linear cryptanalysis is to replace the differential part of the attack by rotational-XOR (RX) differentials. Let \(E = E_1 \circ E_0\) be an encryption function.

XCR结构是一种新增的ARX（加法、旋转和异或-OR）设计，提议用以增强密码学安全伪随机数生成器（CSPRNGs）的随机性和安全性。 它包含了三种主要操作：异或（XOR）用于状态混合、使用非理性数的常数加法引入随机性、以及位旋转用于扩散和打乱位。 这些操作因其简单性、高效率、以及在不增加算法复杂度的情况下提高随机性和安全性而被选用。 XOR操作结合了CSPRNG的状态与随机数据，这些随机数据可以从密钥、随机数或计数器等关键元素中获得。 常数加法 …

2022年3月29日 · 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 and the injection of constants.

2022年3月31日 · Rotational-XOR (RX) 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 constants.

Our research proposes a novel approach to identify DL-based RX distinguishers, by adapting the evolutionary algorithm presented in the work of Bellini et al. to determine optimal values for translation (δ) and rotation ofset (γ) parameters for RX pairs.

XOR cryptanalysis is a statistical technique to attack ARX primitives. In this paper, a computer tool to speed up and make easier the security evaluation of ARX block ciphers against rotational-XOR cryptanalysis is
