Findings

Protocol enables secure key distribution with an untrusted third party.

Uses entanglement swapping between Bell states for protocol design.

First to address semi-quantum key distribution in this environment.

Abstract

This paper proposes the first mediated semi-quantum key distribution in randomization-based environment with an untrusted third party(TP) who has the complete quantum capabilities to help two classical users to establish a secure key. The entanglement swapping between the collapsed qubits of Bell states and the Bell states is used to facilitate the design of the RSQKD protocol.
