Semi-quantum private comparison protocol under an almost-dishonest third party

TL;DR

This paper introduces a semi-quantum private comparison protocol enabling two classical parties to securely compare secrets with an almost-dishonest third party, ensuring privacy and security against common attacks.

Contribution

It is the first protocol of its kind allowing classical participants to perform private comparison under an almost-dishonest third party.

Findings

Protocol is secure against well-known attacks

Allows classical participants to compare secrets securely

Operates under an almost-dishonest third-party model

Abstract

This study presents the first semi-quantum private comparison protocol under an almost-dishonest third party. The proposed protocol allows two classical participants to compare their secret information without compromising it's privacy. The security analyses indicate that the protocol is free from several well-known attacks.
