Quantum-inspired algorithms represent a burgeoning field within cryptography, aiming to enhance the security of lattice-based systems by exploiting subtle quantum phenomena. This paper explores the design of novel quantum-inspired algorithms specifically tailored to the unique properties of lattice structures, focusing on enhancing resistance to known attacks. The core claim centers around developing algorithms that leverage entanglement and superposition to improve the robustness of lattice-based cryptography. We propose a framework for algorithm design, detailing the key steps involved in identifying and utilizing quantum-inspired features within lattice cryptography. The paper concludes with a discussion of the potential implications and challenges of this approach.

ABSTRACT Historically, the hypertext transfer protocol (HTTP) and hypertext transfer protocol secure (HTTPS) have been vital tools for web communication, serving to assure the safety and transmission of data in conventional networks. However, HTTPS protects sensitive information, like login passwords and personal details, from interception by unauthorized entities during Internet browsing. It fundamentally creates a secure link for digital communication. In spite of this, the introduction of quantum computing and quantum Internet has brought to light the limitations of classical protocols (i.e., HTTP and HTTPS) in terms of scalability, performance, and security. This has led to the investigation of quantum alternatives, such as quantum cryptography‐inspired hypertext transfer protocol (QCHTTP). In this paper, a general architecture model belonging to QCHTTP is proposed. Furthermore, a comparative study on HTTP, HTTPS, and QCHTTP is provided along with the features of these protocols that are highlighted. Furthermore, the challenges related to QCHTTP are discussed. Next, various applications of QCHTTP are discussed. The practical implementation of QCHTTP is also provided. Finally, the work is concluded with some important remarks and future research directions associated with QCHTTP.

Quantum computing provides the pathway to dismantle the security provided by cryptography especially classical public-key systems due to the emergence of Shor’s algorithm. This emerging threat necessitates the development of new security paradigms that are quantum-resistant. Consequently, two new approaches have emerged as prominent solutions, namely Quantum Key Distribution (QKD), which relies on quantum mechanical principles for security, and Post-Quantum Cryptography (PQC), which relies on classical cryptography for quantum resistance. This paper presents an extensive analysis of the global research trends in quantum cryptography and post-quantum cryptographic algorithms by incorporating the use of both bibliometric analysis and comparative analysis. The paper relies on a dataset collected from the Web of Science database from 2010 to 2025. The findings of the paper demonstrate an increase in scientific production in the field of quantum cryptography, with post-quantum cryptography emerging as a new dominant area coinciding with standardization by NIST, whereas quantum key distribution continues to evolve with new developments in quantum communication.
