A Chaos‐Driven Image Encryption Method With Möbius Transformations and Finite‐Ring Diffusion

open access: yesEngineering Reports, Volume 8, Issue 11, November 2026.
This paper presents a lightweight yet highly secure image encryption framework integrating chaotic dynamics, HKDF‐S3 key expansion, and Möbius‐Affine transformations. The proposed scheme achieves strong confusion and diffusion with minimal computational cost, demonstrating high resistance to differential and chosen‐plaintext attacks through dynamic key

From Sealed to Anchored: What a Consortium Ledger Adds to HMAC-Sealed IoT Audit Logs in Ambient Assisted Living

open access: yesApplied Sciences
A symmetric integrity seal is worth exactly what its key is worth. Any party holding the keyed-hash (HMAC) key of an Internet of Things (IoT) audit trail can forge a record, re-seal a modified one, and leave no cryptographic trace, so an HMAC-sealed log ...

Energy and memory consumption of SHA256 algorithm [PDF]

open access: yes, 2022
L'efficienza dei computer ha un limite inferiore dettato dal principio di Landauer. La distruzione di una qualsiasi informazione ha un costo energetico per la dissipazione dei bit che la formavano.

Centralised Key Management System Architecture for Topology‐Aware and Quantum‐Resilient Security in QKD‐Integrated SDN Control Planes

open access: yesIET Quantum Communication, Volume 7, Issue 1, January/December 2026.
This paper was not transferred from another journal. ABSTRACT Software‐defined networking (SDN) consolidates network control at a centralised controller, making the southbound TLS‐protected channel between the controller and OpenFlow switches the principal security boundary of the entire network.
