Concurrency and Computation: Practice and Experience, Volume 38, Issue 15, August 2026.ABSTRACT This paper presents MusicoCrypt, a context‐bound music‐modulated stream‐encryption framework that incorporates audio‐derived public side information into a pseudorandom‐function‐centered encryption workflow. A shared reference recording is processed using a pitch‐tracking pipeline, and ordered note pairs are encoded as residues in ℤ132 ...

Secure Decentralized Key Relaying via Random Walks in Dynamic Semi‐Trusted QKD Networks
Advanced Quantum Technologies, Volume 9, Issue 8, August 2026.Quantum Key Distribution (QKD) provides point‐to‐point, information‐theoretically secure session keys, but distance limitations require trusted relays between remote parties. Can quantum keys be relayed without trusting every intermediate node or depending on a central controller?

Journal of Evaluation in Clinical Practice, Volume 32, Issue 5, August 2026.ABSTRACT Background Clinical ethics scholarship on deepfakes has focused primarily on patients as targets of synthetic deception, in which fabricated audiovisual material alters patient beliefs about clinicians and care. This focus neglects the reverse epistemic vulnerability: clinicians themselves as recipients of synthetic, adversarially generated ...
