“…By generalizing the Bell state measurement (BSM) to a GHZ state measurement (GHZ-SM), the proposed protocol could be extended to authenticate more than one user and be used as a multy-party QKD, be used in quantum secret sharing applications or with semiQKD for the interconnectivity of networks. [66,67] An additional advantage of the approach we present over other mdiQKD is that, in crowded environments with many users, it is simpler to have one trusted gateway (Charlie) than many trusted users.…”

Bell‐GHZ Measurement‐Device‐Independent Quantum Key Distribution

In this work, a one‐sided measurement‐device‐independent quantum key distribution protocol that uses Bell and Greenberger–Horne–Zeilinger (GHZ) states is proposed. The protocol considers three parties: Alice and Bob, who will share the key at the end of the protocol; and Charlie, who plays the role of facilitating the key distribution without having access to the key itself. Alice and Charlie are trusted users, while Bob is uncharacterized. The protocol is asymmetrical, meaning that Alice sends one qubit while Bob sends two; this allows Bob to identify himself via a previously assigned ID; if this authentication fails, the key distribution also will.

“…Liu et al [148] use an untrusted quantum server that try to steal session keys. Currently, various quantum states and technologies are used and to devise novel protocoles [149], [150], [151], [152], [153], [155]. Additionally, some authors analyze the security vulnerabilities of SQKD [156], [157], [158].…”

<p>Quantum computing is an emerging field of research that can provide a “quantum leap” in terms of computing performance and thereby enable many new exciting healthcare applications such as rapid DNA sequencing, drug research and discovery, personalized medicine, molecular simulations, diagnosis assistance, efficient radiotherapy. In this paper, we provide a taxonomy of existing literature on quantum healthcare systems and identify the key requirements of quantum computing implementations in the healthcare paradigm. We also provide a through exploration of the application areas where quantum computing could transform traditional healthcare systems. Finally, we perform an extensive study of quantum cryptography from the perspective of healthcare systems to identify security vulnerabilities in traditional cryptography systems.</p>

“…The process of authentication and key sharing is performed simultaneously to provide a sustainable flow of data. Semi-QKD was proposed in [96] where Charlie, as the third party prepares Green-Horne-Zeilinger (GHZ) states, divides them into a sequence and inserts decoy states into the sequence. Then, the quantum Alice requests the sequence of GHZ states and shares it with classical Bob.…”

Quantum Key Distribution for 5G Networks: A Review, State of Art and Future Directions

2022

View full text Add to dashboard Cite

In recent years, 5G networks and services become progressively popular among telecommunication providers. Simultaneously, the growth in the usage and deployment of smartphone platforms and mobile applications have been seen as phenomenal. Therefore, this paper discusses the current state of the art of 5G technology in the merger of unconditional security requirements referred to as Quantum Cryptography. The various domain of Quantum Cryptography is illustrated including the protocols available, their functionality and previous implementation in real networks. This paper further identifies research gaps covering critical aspects of how Quantum Cryptography can be realized and effectively utilized in 5G networks. These include improving the current technique in Quantum Cryptography through efficient key distribution and message sharing between users in 5G networks.
