Cryptographical Properties of Ising Spin Systems
, 2000 The relation between Ising spin systems and public-key cryptography is investigated using methods of statistical physics. The insight gained from the analysis is used for devising a matrix-based cryptosystem whereby the ciphertext comprises products of ...

Applications of single-qubit rotations in quantum public-key cryptography
, 2008 We discuss cryptographic applications of single-qubit rotations from the perspective of trapdoor one-way functions and public-key encryption. In particular, we present an asymmetric cryptosystem whose security relies on fundamental principles of quantum ...

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.
