Rotational cryptanalysis of round-reduced Keccak [PDF]

, 2013
In this paper we attack round-reduced Keccak hash function\ud with a technique called rotational cryptanalysis. We focus on Keccak variants proposed as SHA-3 candidates in the NIST’s contest for a new standard of cryptographic hash function.

A Secure and Efficient Framework for ECG Signal Digitization and Encryption for Internet of Medical Things Applications

Healthcare Technology Letters, Volume 13, Issue 1, January/December 2026.
This paper proposes a secure electrocardiogram (ECG)‐processing framework that digitises ECG waveforms from clinical paper or image‐based records and encrypts them using a dual chaotic cryptographic scheme. The method supports both extracted and native digital signals, ensuring strong security and interoperability for Internet of Medical Things ...

Hyperchaos‐Driven 3D RGB Image Scrambling and Encryption for Multi‐Image Security

IET Image Processing, Volume 20, Issue 1, January/December 2026.
The proposed encryption scheme scrambles N colour images by stacking them into a three‐dimensional red, green, blue image, generating a secure 256‐bit key using SHA‐256 and a user‐provided salt, and applying a five‐dimensional multi‐wing hyperchaotic system to produce random key streams.

A Novel Hybrid Image Encryption Scheme Using Henon Map for Secure Image Communication

IET Information Security, Volume 2026, Issue 1, 2026.
The combination of chaos theory and cryptographic methodologies constitutes a pivotal aspect of the information security. Owing to certain attributes of images, like their large data capacity and significant redundancy, image encryption needs specialized techniques instead of conventional text encryption.

Cryptanalysis of ARMADILLO2 [PDF]

, 2011
ARMADILLO2 is the recommended variant of a multi-purpose cryptographic primitive dedicated to hardware which has been proposed by Badel et al. in [1]. In this paper we propose a meet-in-the-middle technique that allows us to invert the ARMADILLO2 function.

Biclique Cryptanalysis on the Full Crypton-256 and mCrypton-128

Journal of Applied Mathematics, 2014
Biclique cryptanalysis is an attack which reduces the computational complexity by finding a biclique which is a kind of bipartite graph. We show a single-key full-round attack of the Crypton-256 and mCrypton-128 by using biclique cryptanalysis.
