Abstract
With the rapid development of information technology, cybersecurity faces unprecedented challenges. Traditional encryption algorithms are becoming increasingly vulnerable in the face of the formidable computational power of quantum computing. In contrast, quantum key distribution (QKD) algorithms, which ensure absolutely secure information transmission based on the principles of quantum mechanics, have emerged as a critical technology for addressing cybersecurity issues. This study aims to explore the implementation paths and challenges of QKD algorithms in cybersecurity, providing theoretical foundations and technical support for building a more secure and reliable network environment. By conducting an in-depth analysis of typical QKD algorithms such as the BB84 protocol and the E91 protocol, and considering the characteristics of actual network architectures, this research proposes an improved QKD scheme integrated with an authentication mechanism. This scheme not only effectively resists eavesdropping attacks but also achieves accurate user identity verification. Experimental results demonstrate that the improved QKD algorithm exhibits higher key generation efficiency and security under various network conditions, with a significantly reduced error rate. Innovatively integrating authentication into the QKD process, this study addresses the issue of user identity confirmation in traditional QKD, offering new insights for practical applications of QKD algorithms and contributing significantly to the widespread adoption of quantum communication technologies in the field of cybersecurity.
