Exploring Secret Keys in Searching Integral Distinguishers Based on Division Property

IACR Transactions on Symmetric Cryptology, 2020
Division property proposed by Todo at EUROCRYPT 2015 is a generalized integral property. Then, conventional bit-based division property (CBDP) and bitbased division property using three subsets (BDPT) were proposed by Todo and Morii at FSE 2016.

Optimal Differential Trails in SIMON-like Ciphers

IACR Transactions on Symmetric Cryptology, 2017
In the present paper, we propose an automatic search algorithm for optimal differential trails in SIMON-like ciphers. First, we give a more accurate upper bound on the differential probability of SIMON-like round function.

Rotational-XOR Cryptanalysis of Simon-like Block Ciphers [PDF]

, 2020
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 using modular addition, cyclic rotation, XOR, and the injection of constants.

Fast implementations of ARX-based lightweight block ciphers (SPARX, CHAM) on 32-bit processor

International Journal of Distributed Sensor Networks, 2019
Recently, many lightweight block ciphers are proposed, such as PRESENT, SIMON, SPECK, Simeck, SPARX, GIFT, and CHAM. Most of these ciphers are designed with Addition–Rotation–Xor (ARX)-based structure for the resource-constrained environment because ARX ...

Improved Integral Attacks on SIMON32 and SIMON48 with Dynamic Key‐Guessing Techniques

Security and Communication Networks, Volume 2018, Issue 1, 2018., 2018
Dynamic key‐guessing techniques, which exploit the property of AND operation, could improve the differential and linear cryptanalytic results by reducing the number of guessed subkey bits and lead to good cryptanalytic results for SIMON. They have only been applied in differential and linear attacks as far as we know.

Secure Data Encryption for Cloud‐Based Human Care Services

Journal of Sensors, Volume 2018, Issue 1, 2018., 2018
Sensor network services utilize sensor data from low‐end IoT devices of the types widely deployed over long distances. After the collection of sensor data, the data is delivered to the cloud server, which processes it to extract useful information. Given that the data may contain sensitive and private information, it should be encrypted and exchanged ...
