Multiparty Quantum Key Agreement Based on Quantum Search Algorithm

Abstract: Quantum key agreement is an important topic that the shared key must be negotiated equally by all participants, and any nontrivial subset of participants cannot fully determine the shared key. To date, the embed modes of subkey in all the previously proposed quantum key agreement protocols are based on either BB84 or entangled states. The research of the quantum key agreement protocol based on quantum search algorithms is still blank. In this paper, on the basis of investigating the properties of quantum searc… Show more

“…In the security analysis section of this paper, the proposed protocol was able to defend external eavesdropper attacks and internal malicious participant attacks. In the consumption comparison section, the performance of the proposed protocol was shown to be superior to the compared MQKA protocols 5355,57,58,60,61 .…”

“…Without losing fairness, each protocol agrees on a 180 N bit key, where N is the number of participants. Because of different transmission methods, those protocols 5355,5760 using unicast transmission require more qubits for channel checking than in Zeng et al . 61 and the proposed protocol using multicast transmission.…”
