“…The original one time pad QSDC scheme is proposed by Long et al [39], it realizes the information direct communication using single photons. In [72], two robust QSDC schemes are presented, one is implemented with a quantum one-time pad over a collectivedephasing noise channel, the other one is to build a quantum one-time pad over a collective-rotation. The information is encoded using two unitary operations on each logical qubit, each logical qubit is implemented with two photonstwo physical bits, entangled photon pairs can be used for one logical qubit.…”

“…QSDC has a good application prospect because it is complete quantum but the communication process should be more secure than the security for QKD. QSDC protocols have been proposed with different implementation ways [38][39][40][41][42][43][44][45][46][47][48].…”

In this review article, we will review the recent process of quantum communications. In the past decades, there are many developments in quantum communication, for instance, quantum key distribution, quantum teleportation, quantum secure direct communication, deterministic secure quantum communication, quantum secret sharing and so on. And we focus our attention on the recent developments in quantum communication protocols. The principles in quantum mechanics provide novel ways for quantum information transmission and processing, such as quantum computation and quantum communication. In the past decades, quantum information processing has emerged as a promising technology with strategic importance. Because of the peculiar properties of quantum systems, quantum computers possess enormous power that is superior to classical computer. Using quantum computer, factorization of an integer can be accomplished in polynomial time with the Shor algorithm [1]. And we can find a marked item with high probability from an unsorted database with a square-root speedup with the Grover algorithm [2]. In the past decades, the field of quantum information processing and quantum computation have attracted much attention [3][4][5][6]. With these quantum algorithms and a quantum computer, many classical cryptography protocols can be attacked. Thus it is vital to find new cryptographic systems for defending against these attacks.In the following years, there are many branches of quantum communications that are generated which provides us secure ways of communications, such as quantum key distribution (QKD), quantum teleportation, quantum secure direct communication, quantum secret sharing and so on. QKD provides a secure way to distribute secret keys between distant *Corresponding author (email: wangchuan@bupt.edu.cn) users which solves the problem for secure distributing of keys in the classical one-time-pad protocol [7]. However, quantum communication offers more power than QKD. Quantum secret sharing (QSS) distributes secret keys to two or more shared users [8], which can be viewed as the quantum key distribution between multi-users. Quantum teleportation is a basic ingredient in quantum information architectures [9,10]. The principle of quantum teleportation is to transfer an unknown state to the legal user at a distant distance. Quantum secure direct communication (QSDC) offers direct communication of secret messages between distant users, which saves completely the need for another classical communication as in the QKD case. In recent years, there have been considerable developments from researchers in the design of quantum communication protocols. In this article, we will focus on these developments in quantum communications. A brief history and key techniques of quantum communicationQKD provides an unconditional secure way of information exchange between two distant users. The first QKD protocol is proposed by Bennett and Brassard [7], called the BB84 protocol. In 1992, Bennett proposed a simplified version of

“…However, noise is inevitable in practice, which will affect the security and fidelity of the information transmitted. Hence, many researchers turn to research practical QSDC protocols [29][30][31][32][33][34][35]. In 2011, Liu et al [36] presented a high-capacity quantum secure direct communication protocol with single photons in both the polarization and the spatial-mode degrees of freedom.…”

ABSTRACT Combining the idea of quantum secure communication and quantum homomorphic signature, we propose a quantum secure communication protocol with signature via EPR pairs, in which the identities of the sender and the recipient could be certified and the integrity of the message transmitted is guaranteed according to their signatures. Comparing with the previous quantum secure communication scheme without signature, our protocol is not only feasible in practice but also can effectively guarantee the reliability and security of the quantum communication. The security of the protocol is analyzed.

“…With the continuous study by researchers, there are many efficient QSDC protocols that have been presented in recent years, including protocols without using entanglement [12,13], and protocols using entanglement [14][15][16][17]. In addition, methods using two-way communication and quantum one-time pad are introduced to improve security [18][19][20][21][22].…”

A novel quantum secure direct communication protocol based on four-particle genuine entangled state and quantum dense coding is proposed. In this protocol, the four-particle genuine entangled state is used to detect eavesdroppers, and quantum dense coding is used to encode the message. Finally, the security of the proposed protocol is discussed. During the security analysis, the method of entropy theory is introduced, and two detection strategies are compared quantitatively by comparing the relationship between the maximal information that the eavesdroppers (Eve) can obtain, and the probability of being detected. Through the analysis we can state that our scheme is feasible and secure.
