“…It has been shown that use of multicast quantum states lowers quantum channel capacity [35]. The typical network architecture used for quantum multicast is not the same as that in classical network multicast scenario since single qubits may not be replica ted when sent to different parties [36].…”

Quantum computing and quantum communications are exciting new frontiers in computing and communications. Indeed, the massive investments made by the governments of the US, China, and EU in these new technologies are not a secret and are based on the expected potential of these technologies to revolutionize communications, computing, and security.In addition to several field trials and hero experiments, a number of companies such as Google and IBM are actively working in these areas and some have already reported impressive demonstrations in the past few years. While there is some skepticism about whether quantum cryptography will eventually replace classical cryptography, the advent of quantum computing could necessitate the use of quantum cryptography as the ultimate frontier of secure communications. This is because, with the amazing speeds demonstrated with quantum computers, breaking cryptographic keys might no longer be a daunting task in the next decade or so. Hence, quantum cryptography as the ultimate frontier in secure communications might not be such a far-fetched idea.It is well known that Heisenberg's Uncertainty Principle is essentially a "negative result" in Physics and Quantum Mechanics. It turns out that Heisenberg's Uncertainty Principle, one of the most interesting results in Quantum Mechanics, could be the theoretical basis and the main scientific principle behind the ultimate frontier in quantum cryptography or secure communications in conjunction with Quantum Entanglement. In this survey paper, we provide a simple and accessible tutorial survey for engineers and computer scientists on the basics of Quantum Communications, foundations of Quantum Entanglement (QE), the mechanisms that can be used to generate QE, metrics to measure QE, Requirements for Channel Capacity and Noise, etc. While the primary application of QE considered is in Quantum Key Distribution for secure communications, other applications using entanglement protocols and their relevant considerations are also described.

“…This centralized approach encounters serious problems due to high communication and computation cost. This cost increase was due to the performance of some exponentiation operations like transmitting messages confidentiality and authentication between the multicast group members' and centralized server [11]. Some of the challenges that are encountered by this centralized GKM are lack of scalability, operational inefficiency, and Inability to support multiple membership change.…”

Abstract: The most appropriate communication mechanism for transfer of packets from one source to another is multicast IPv6 communication. Nowadays, multicast communication plays a major role in a large number of communication applications. In this multicast communication, the message privacy attains a highest position. The members of multicast are dynamic so they permit the host members to enter and depart the cluster without the permission of remaining group members and, it can't provide any transfer without the interference of host, this may reduce the performance. For security enhancement in multicast communication Group Key Management (GKM) was introduced.There are three different approaches in GKM and they were mainly involved to overcome the issues of host mobility in multicast communication. The challenges that are encountered by these GKM approaches their requirements and challenges was also discussed in this paper. Finally, some questions and their explanations were provided along with it. These GKM approaches will improve the privacy of multicast communication. So, the packets can deliver to the group members without any interference.

“…First, the GHZ states were used for authentication purposes; the remaining GHZ states were used to transmit the secret message directly. In 17 , the architecture for a centralized multicast scheme was proposed basing on a hybrid model of quantum key distribution and classical symmetric encryption. The proposed scheme solved the key generation and the management problem using a single entity called centralized Quantum Multicast Key Distribution Centre.…”

“…In the latter, the classical information can be encoded and transmitted based on one quantum bit and on the maximally shared quantum entanglement among the distant parties as each quantum bit can transmit two classical bits 11,12 . A number of approaches and prototypes can be used to exploit quantum principles in order to secure communication between two parties and multiple parties [13][14][15][16][17] . While these approaches use different techniques to ensure private communication among authorized users, most of them still depend on the generation of secret random keys 18,19 .A quantum secret communication concept has recently been introduced; it is a kind of quantum communication in which secret messages can be transmitted through a quantum channel with or without additional classical communications .…”

In this paper, we generalize a secured direct communication process between N users with partial and full cooperation of quantum server. So, N − 1 disjointed users u1, u2, …, uN−1 can transmit a secret message of classical bits to a remote user uN by utilizing the property of dense coding and Pauli unitary transformations. The authentication process between the quantum server and the users are validated by EPR entangled pair and CNOT gate. Afterwards, the remained EPR will generate shared GHZ states which are used for directly transmitting the secret message. The partial cooperation process indicates that N − 1 users can transmit a secret message directly to a remote user uN through a quantum channel. Furthermore, N − 1 users and a remote user uN can communicate without an established quantum channel among them by a full cooperation process. The security analysis of authentication and communication processes against many types of attacks proved that the attacker cannot gain any information during intercepting either authentication or communication processes. Hence, the security of transmitted message among N users is ensured as the attacker introduces an error probability irrespective of the sequence of measurement.
