A Secure Color Image Encryption Method Using Genetic Algorithm–Based Pixel Permutation and Multimap Chaotic Diffusion

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
Images transmitted across open networks, such as the Internet, are inherently vulnerable to eavesdropping, unauthorized access, and data tampering. Sensitive image categories, including medical, military, biometric, and legal images, often require a higher level of protection than public protocols provide. Moreover, the large size, high redundancy, and

Eliminating Centralized Trust in VANETs: A Blockchain‐Assisted SSL‐PUF Authentication and Cross‐Domain Key Agreement Scheme

International Journal of Distributed Sensor Networks, Volume 2026, Issue 1, 2026.
Vehicular ad hoc networks (VANETs) enable secure vehicle‐to‐vehicle (V2V) and vehicle‐to‐infrastructure (V2I) communications but still rely heavily on centralized trusted authorities, creating scalability limitations, single‐point failures, and increased authentication latency.

Intelligent Sky Computing: A DDPG‐Based Joint Optimization Scheme for Privacy‐Aware Task Offloading in Multi‐UAV Networks

International Journal of Distributed Sensor Networks, Volume 2026, Issue 1, 2026.
Exploiting privacy‐aware user task offloading in a multi‐UAV–assisted edge computing system offers a new approach to reduce and balance energy consumption and latency. However, the complexity and variability of operating scenarios can make privacy‐aware user task offloading strategies challenging. This paper examines a system with multiple ground users,

Bridging the Gap: Achieving Seamless Interoperability Between Ethereum‐Based Blockchains Using Inter‐Blockchain Communication Protocols

Software: Practice and Experience, Volume 55, Issue 11, Page 1749-1772, November 2025.
ABSTRACT Introduction The popularization of blockchain‐based applications made evident a critical challenge, namely the inherent isolation of these decentralized systems, akin to the disconnected and technologically diverse local area networks of the 1970s. This lack of interoperability limits the potential for widespread adoption and innovation in the

Leveraging Blockchain and Smart Contracts to Combat Greenwashing in Sustainable Development

Sustainable Development, Volume 33, Issue 4, Page 5874-5889, August 2025.
ABSTRACT Blockchain technology, when combined with smart contracts, enables buyers to distinguish between greenwashed and genuinely eco‐friendly products. The presence of counterfeit items can severely impact supply chains by diminishing brand value, eroding consumer confidence, and undermining market trust.
