“…Here, it is worth mentioning that permutation operator is not a unique way to circumvent these attacks, a prior shared key will also ensure the security of the protocol. A similar strategy of using a prior shared key has been observed in a few protocols in the past [27]. We would like to emphasize here that employing a key for security is beyond the domain of direct communication.…”

Semi-quantum protocols that allow some of the users to remain classical are proposed for a large class of problems associated with secure communication and secure multiparty computation. Specifically, first time semi-quantum protocols are proposed for key agreement, controlled deterministic secure communication and dialogue, and it is shown that the semi-quantum protocols for controlled deterministic secure communication and dialogue can be reduced to semi-quantum protocols for ecommerce and private comparison (socialist millionaire problem), respectively. Complementing with the earlier proposed semi-quantum schemes for key distribution, secret sharing and deterministic secure communication, set of schemes proposed here and subsequent discussions have established that almost every secure communication and computation tasks that can be performed using fully quantum protocols can also be performed in semi-quantum manner. Further, it addresses a fundamental question in context of a large number problems-how much quantumness is (how many quantum parties are) required to perform a specific secure communication task? Some of the proposed schemes are completely orthogonal-state-based, and thus, fundamentally different from the existing semi-quantum schemes that are conjugate-coding-based. Security, efficiency and applicability of the proposed schemes have been discussed with appropriate importance.Keywords: Semi-quantum protocol, quantum communication, key agreement, quantum dialogue, deterministic secure quantum communication, secure direct quantum communication. * plored using quantum resources.

Alternatively, whether all the users involved in a secure communication scheme are required to be quantum in the sense of their capacity to perform quantum measurement, prepare quantum states in more than one mutually unbiased basis (MUBs) and/or the ability to store quantum information? Efforts to answer the first question have led to a set of orthogonal-state-based schemes [5,[31][32][33][34], where security is obtained without using our inability to simultaneously measure a quantum state using two or more MUBs. These orthogonal-state-based schemes [5,[31][32][33][34] have strongly established that any cryptographic task that can be performed using a conjugate-coding-based scheme can also be performed using an orthogonal-state-based scheme. Similarly, efforts to answer the sec...

“…Specifically, if a maximally densecodable quantum state is used as quantum channel, the encoding operations form a group under multiplication. This point will be further discussed in detail in the forthcoming sections.Recently, considerable efforts have also been made to avoid information leakage in quantum dialogue protocols (see [16,21,22,24] and reference therein). Some efforts have also been made to study the effect of noise on the schemes of QD [30,31,32].…”

A notion of asymmetric quantum dialogue (AQD) is introduced. Conventional protocols of quantum dialogue are essentially symmetric as both the users (Alice and Bob) can encode the same amount of classical information. In contrast, the scheme for AQD introduced here provides different amount of communication powers to Alice and Bob. The proposed scheme, offers an architecture, where the entangled state and the encoding scheme to be shared between Alice and Bob depends on the amount of classical information they want to exchange with each other. The general structure for the AQD scheme has been obtained using a group theoretic structure of the operators introduced in (Shukla et al., Phys. Lett. A, 377 (2013) 518). The effect of different types of noises (e.g., amplitude damping and phase damping noise) on the proposed scheme is investigated, and it is shown that the proposed AQD is robust and uses optimized amount of quantum resources.The birth of quantum cryptography in 1984 [1], followed by its variants steadily paved way for various quantum communication schemes, thereby, establishing its manifold applications (see [2] and references therein). Initial protocols [1,3,4,5] of secure quantum communication were restricted to the designing of protocols for quantum key distribution (QKD), which enables a sender (Alice) to share (distribute) a key with a receiver (Bob). It was later realized that a preshared (pre-distributed) key is not essential for secure quantum communication, and several schemes for secure direct quantum communication were proposed [6,7,8,9,10,11]. These schemes of secure direct quantum communication were mainly of two types: quantum secure direct communication (QSDC) and deterministic secure quantum communication (DSQC). In a QSDC scheme, the receiver can decode an information encoded by the sender without any additional information (classical communication) [6,7,8]. In contrast, in a scheme for DSQC, the receiver requires at least one bit of classical information to decode each bit of the message encoded by the sender [9,10]. Different variants of DSQC and QSDC protocols have been studied in the recent past. Specifically, controlled DSQC has been studied in much detail in the recent past ([11] and references therein). Interestingly, the schemes of DSQC and QSDC are one way schemes in the sense that these schemes only allow Alice to communicate a message to Bob, but does not allow Bob to do the same. In contrast, in daily life, one often need bidirectional communication, where two parties can simultaneously communicate messages to each other, an example been classical communication via telephone. Keeping this in mind, a scheme for simultaneous bidirectional quantum communication was introduced by Ba An [12] in 2004, and was referred to as "quantum dialogue (QD)". However, it was found that the Ba An scheme was insecure under intercept-resend attack [9]. In Ref. [9], an effort was made to modify the original Ba An scheme to provide a secure * 1 scheme for QD. However the effort was not successful a...

“…In this protocol, a series of ordered two-quantum entangled states are used as quantum information channels for direct and simultaneous exchange of secret information. In addition, a secret key string is shared between communicators to overcome information leakage, but the efficiency of other schemes is very low and cannot meet the requirements of information protection [1]. Lin and Lin investigated the possibility of unintentional and involuntary disclosure of personal information on Facebook.…”

In recent years, the Internet of Things technology, which is an important part of the new generation of information technology, has developed rapidly. The Internet provides more comprehensive conditions for resource sharing at all levels of society. However, while the Internet provides convenience to the society and users, corporate human resource information security has been increasingly impacted, and the channels for personal information leakage on the Internet are also emerging endlessly and in various ways. This article studies the role of Internet of Things security in the management of enterprise human resource information leakage, in order to use Internet of Things security technology to reduce the possibility of information leakage and play the role of efficient and safe management of enterprise human resource information. Therefore, in the experiment, aiming at the problem of personnel information privacy, a privacy protection method based on secure network coding is proposed. This method uses the hybrid coding mechanism of network coding to effectively resist traffic analysis attacks, thereby protecting the information privacy of nodes. Aiming at the threat of data pollution and malicious attacks in the network coding process, GPU host is introduced, and a network coding method based on the CUDA parallel algorithm is proposed to improve the throughput of the network. Theoretical analysis and simulation experiments show that the method has good performance in privacy protection, computational overhead, and communication delay. In the final experimental results, it is concluded that with the support of IoT security technology, the average accuracy and recall rate of information privacy leakage detection results are not less than 85%.
