Implementation and Evaluation of Parallel Computing Approaches for Large‐Domain, Process‐Based Hydrologic Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Process‐based hydrologic simulations in large domains generally require intensive computing resources. In this study, we implement various parallelization approaches within a process‐based hydrologic solver, SUMMA, including the Message Passing Interface (MPI), Open Multi‐Processing (OMP), and the Actor Model, to enable high‐performance ...

Design and Implementation of XGBoost‐Based Cyberattack Detection and Blockchain‐Enabled Charging Station

Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.
The charging station (CS) plays a crucial role in charging electric vehicles. Therefore, it is necessary to protect the CS from cyberattacks. This paper proposes an architecture for the security of the EV fleet during charging using the XGBoost model and Hyperledger Fabric to protect battery management systems (BMS) from cyberattacks.

A Robust Reversible Watermarking Algorithm Resistant to Geometric Attacks Based on Tchebichef Moments

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper presents a robust reversible watermarking algorithm based on Chebyshev moments, employing a two‐stage embedding mechanism. The proposed method leverages image block partitioning to embed the copyright watermark and the reversible watermark into non‐overlapping regions located inside and outside the inscribed circle of the image, respectively.

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.

Blockchain‐Enabled Privacy‐Preserving Access Control for EHRs Sharing With Optimized User and Attribute Revocation

IET Information Security, Volume 2026, Issue 1, 2026.
Electronic health records (EHRs) have become a crucial application in cloud computing environments, necessitating advanced privacy‐preserving access control mechanisms. Ciphertext policy attribute‐based encryption (CP‐ABE) is a widely recognized solution for secure access control in outsourced data environments.

(Not Surprising) Attacks on Recent Pairing‐Free Attribute‐Based Encryption Schemes

IET Information Security, Volume 2026, Issue 1, 2026.
The fact that designing secure and efficient identity or attribute‐based encryption (ABE) schemes requires the use of specific algebraic tools like bilinear pairings or lattices is well known in the cryptographic community. However, some journals whose main topics are not cryptographic still publish papers proposing, for instance, ABE schemes in ...
