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

SNR based secure communication via untrusted amplify-and-forward relay nodes using artificial noise
, 2018 A two-phase beamforming solution for secure communication using untrusted relay nodes is presented. To thwart eavesdropping attempts of participant relay nodes, we deliberately introduce artificial noise in the source message. We observe that for certain

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.

International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...

Quantum Network Infrastructure
Advanced Quantum Technologies, Volume 8, Issue 2, February 2025.Quantum computing presents a threat to secure communication. Consequently, novel methods are investigated to address this global challenge, namely post quantum cryptography (PQC) and quantum key distribution (QKD). The image represents the distribution of a wavefunction over the entire world by using satellites in orbit.
