Rotational Bell-State Loop-Back Key Establishment and Agreement Certification for Passive Users
Luis Adrián Lizama-Pérez, Luis Adrián Lizama-Pérez
Server-aided Bell-state networks with sequential local encoding are an established approach to mediated key distribution. Against this background, we study a Loop-Back architecture…

A Bell-State Extension of Loop-Back Quantum Key Distribution
Luis Adrián Lizama-Pérez
Bidirectional quantum key distribution (QKD) protocols face persistent challenges related to classical disclosure, confinement of the signal space to predictable subspaces, and lim…
