The security of digital communication and information systems is mostly dependent on block ciphers. ARX-based ciphers are widely used due to their simplicity and efficiency. This paper provides an exhaustive cryptanalysis of a subset of ARX-based blo

Differential Cryptanalysis of Round-Reduced SPECK Suitable for Internet of Things Devices

Autor: Ashutosh Dhar Dwivedi, Pawel Morawiecki, Gautam Srivastava

Publikováno v: IEEE Access, Vol 7, Pp 16476-16486 (2019)

In this paper, we focus on differential cryptanalysis of a lightweight ARX cipher. These ciphers use three simple arithmetic operations, namely, modular addition, bitwise rotation, and exclusive-OR, and therefore, are designed very well to perform ov

Autor: Ashutosh Dhar Dwivedi, Gautam Srivastava

Publikováno v: Dwivedi, A D & Srivastava, G 2023, ' Security analysis of lightweight IoT encryption algorithms : SIMON and SIMECK ', Internet of Things (Netherlands), vol. 21, 100677 . https://doi.org/10.1016/j.iot.2022.100677

This paper presents the differential cryptanalysis of two lightweight ciphers, namely, SIMON and SIMECK. The first cipher SIMON was presented by the U.S. National Security Agency in 2013 and the second one SIMECK was presented by researchers from the

Finding Differential Paths in ARX Ciphers through Nested Monte-Carlo Search

Autor: Dwivedi Ashutosh Dhar, Paweł Morawiecki, Sebastian Wójtowicz

Publikováno v: International Journal of Electronics and Telecommunications, Vol vol. 64, Iss No 2 (2018)

We propose the adaptation of Nested Monte-Carlo Search algorithm for finding differential trails in the class of ARX ciphers. The practical application of the algorithm is demonstrated on round-reduced variants of block ciphers from the SPECK family.
