Fundamental Two-Party Quantum Secret Sharing Protocol without Quantum Entanglement

Abstract

Quantum key distribution (QKD) protocol techniques are used in the distribution of keys using the laws of physics. Quantum secret sharing (QSS), quantum secure direct communication, and quantum teleportation, which are all included under QKD, are used to share or distribute a secure key in a quantum environment. In QSS, we share a key based on the quantum properties of light. We emphasize cooperation between communicating parties to eliminate untrustworthy members and to improve the strength of the key. The results obtained showed that using the proposed method, it is difficult for eavesdroppers to obtain the key.
