“…It relies on the hardness of lattice problems, which, to date, have no efficient solving algorithm on quantum computers. The advantage of this approach lies in its presumed resistance to quantum attacks, offering a secure alternative to traditional systems (Rewal et al, 2023). However, the downside includes larger key sizes and increased computational overhead, which could be a hindrance in environments with limited resources (Shaller, Zamir and Nojoumian, 2023).…”

With the constantly advancing capabilities of quantum computers, conventional cryptographic systems relying on complex math problems may encounter unforeseen vulnerabilities. Unlike regular computers, which are often deemed cost-ineffective in cryptographic attacks, quantum computers have a significant advantage in calculation speed. This distinction potentially makes currently used algorithms less secure or even completely vulnerable, compelling the exploration of post-quantum cryptography (PQC) as the most reasonable solution to quantum threats. This review aims to provide current information on applications, benefits, and challenges associated with the PQC. The review employs a systematic scoping review with the scope restricted to the years 2022 and 2023; only articles that were published in scientific journals were used in this paper. The review examined the articles on the applications of quantum computing in various spheres. However, the scope of this paper was restricted to the domain of the PQC because most of the analyzed articles featured this field. Subsequently, the paper is analyzing various PQC algorithms, including lattice-based, hash-based, code-based, multivariate polynomial, and isogeny-based cryptography. Each algorithm is being judged based on its potential applications, robustness, and challenges. All the analyzed algorithms are promising for the post-quantum era in such applications as digital signatures, communication channels, and IoT. Moreover, some of the algorithms are already implemented in the spheres of banking transactions, communication, and intellectual property. Meanwhile, despite their potential, these algorithms face serious challenges since they lack standardization, require vast amounts of storage and computation power, and might have unknown vulnerabilities that can be discovered only with years of cryptanalysis. This overview aims to give a basic understanding of the current state of post-quantum cryptography with its applications and challenges. As the world enters the quantum era, this review not only shows the need for strong security methods that can resist quantum attacks but also presents an optimistic outlook on the future of secure communications, guided by advancements in quantum technology. By bridging the gap between theoretical research and practical implementation, this paper aims to inspire further innovation and collaboration in the field.

A three-party authenticated key exchange protocol enables two entities to agree on a session key with the help of a dedicated server over public channel. Shor's algorithm is a big threat for existing authenticated key exchange protocols. Lattice based cryptography plays a very important role in designing authentication and key agreement secure against the threat of quantum attacks. However, it is not easy job to design quantum resistant password based three party protocol due to the high demand for security requirements and the limited resources nature of mobile devices.In this article, we have proposed a new post quantum three party key exchange based on ring learning with errors assumption. This protocol is motivated from Islam et al.'s authenticated key exchange protocol. Their protocol is not secure against stolen smartcard attack, password guessing attack, and can't provide user anonymity. The anonymous communication is a big requirement for practical applications like e-healthcare services/smart vehicular communication. This paper also contains the performance analysis of the proposed protocol along with other relevant protocols.

Once the shared secret key is established, three parties can use it for secure communication using symmetric-key encryption AES (128, 192, 256) algorithms or other cryptographic primitives. Although there are few third-party post-quantum authentication and key agreement protocols exist, but the recent studies in this article show that they are not anonymous or cannot provide forward secrecy. Most of the existing protocols enable adversaries to trace the source of messages. Many of third-party AKA schemes based on conventional public-key cryptosystems are vulnerable to quantum computers. Therefore, this paper contains a forward secure three-party postquantum authenticated key establishment protocol for mobile devices. The proposed three-party key exchange protocol establishes an authenticated shared key that can be periodically refreshed to maintain forward secrecy. This protocol enables two parties to establish a shared session key even in the presence of quantum adversaries and enables them to communicate condentially and securely over insecure networks. The protocol is anonymous as both the parties communicate using masked dynamic identities. A contrast study consisting of performance and security assessment is presented, which illustrates the suggested design is more applicable.
