A Piggybank Protocol for Quantum Cryptography

TL;DR

This paper introduces a quantum cryptography protocol based on the piggybank idea, involving two separate communications for secure message encryption and transformation, enhancing security through quantum mechanics principles.

Contribution

It proposes a novel quantum piggybank protocol that separates encryption transformation information from the message, increasing security against eavesdropping.

Findings

The protocol uses two-stage quantum communication.

Deciphering the transformation alone does not compromise security.

The method enhances quantum cryptography security features.

Abstract

This paper presents a quantum mechanical version of the piggy-bank cryptography protocol. The basic piggybank cryptography idea is to use two communications: one with the encrypted message, and the other regarding the encryption transformation which the receiver must decipher first. In the quantum mechanical version of the protocol, the encrypting unitary transformation information is sent separately but just deciphering it is not enough to break the system. The proposed quantum protocol consists of two stages.
