Multiparty Quantum Key Agreement Protocol Based on 2-Qubit Grover Search with swapping
Tzung‐Her Chen · 2024
Huang et al. (2021) introduced a quantum key agreement scheme using a quantum search algorithm. They initially designed a two-party protocol, later extending it to accommodate three-or N-party scenarios. Notably, Huang et al.'s protocol avoids the need for complex quantum technologies such as entangled quantum particles. However, it is observed that Huang et al.'s protocol imposes a burden on a single participant when applied to multiparty scenarios. This paper contends that such centralization to a single participant is suboptimal for multiparty settings. Thus, our work seeks to build upon the foundations laid by Huang et al. in a manner that addresses this limitation, presenting a modified framework tailored to accommodate multiparty scenarios while distributing computational responsibilities more evenly among participants.
