Quantum cryptography technology has gained significant attention as a critical tool for protecting corporate secrets and national information. With the potential obsolescence of traditional encryption methods due to advancements in quantum computing, quantum cryptography is poised to emerge as the sole alternative for safeguarding personal and sensitive information. Consequently, this technology is recognized as a matter of national importance. This paper is the first in Korea to conduct a keyword network analysis of domestic research reports on quantum cryptography, and has academic value by suggesting implications and future research directions. The main keywords and major challenges derived through frequency analysis, centrality analysis, and CONCOR analysis, as well as the future of quantum cryptography technology, can be summarized as follows: First, lightweight and secure quantum cryptography algorithms to strengthen cloud and blockchain security; second, hardware development and standardization for technical implementation of quantum cryptography communication systems; third, strengthening physical infrastructure to ensure security and prevent hacking in photon-based quantum cryptography communications; and fourth, application of quantum cryptography technology to secure national infrastructure and energy management systems and large-scale data processing.
