In today Internet era, confidential information transmitted over an insecure channel. With the
significant development in the area of quantum computing, there is a need for unconditional …

In this paper, we propose a novel secure multi-party quantum summation protocol based on
quantum Fourier transform, where the traveling particles are transmitted in a tree-type mode …

Abstract Sun et al.[Quantum Inf. Process., 2101–2111 (2016)] proposed an efficient MQKA
protocol based on commutative encryption to protect secret key exchange among multiple …

Quantum key agreement (QKA) is an important primitive of quantum cryptography and has
attracted continuous attention. However, in practical QKA, the imperfections of the honest …

As a burgeoning branch of quantum cryptography, quantum key agreement is a kind of key
establishing processes where the security and fairness of the established common key …

Based on four-qubit cluster states, we present a new multi-party quantum key agreement
(QKA) protocol. The proposed protocol makes full use of four-qubit cluster states as quantum …

Quantum key agreement (QKA) is an important branch of quantum cryptography. In this
paper, we propose a mutual authenticated semi-honest key agreement scheme with …

Key agreement is a basic cryptographic primitive, which plays an important role in private
communications. In this work, we propose a measurement-device-independent three-party …

It's conceivable to have a few dishonest participants when you want to exchange a secret
key among participants in a certain network. Due to dishonest participants, a secret key …

Recently, quantum communication has become a very popular research field. The quantum
key agreement (QKA) plays an important role in the field of quantum communication, based …
