Strengthening security in cryptographic protocols in the era of quantum computers

Abstract

This research addresses the escalating security concerns associated with the rapid evolution of quantum computers. With quantum advancements posing potential threats to traditional cryptographic schemes, our study aims to fortify their resilience. By proactively employing anti-quantum algorithms, we seek to secure SSH sessions and storage, thus mitigating the risk of "catch first, decrypt later" attacks. The methodology section provides a detailed overview of the application of these algorithms, introducing an innovative approach to bolster the security of public key distribution in the SSH protocol. Our findings underscore the practical significance of these measures, demonstrating significant enhancements in communication and data integrity protection. In conclusion, our research highlights the critical role of authenticated open channels in cryptographic protocols, offering a comprehensive strategy to anticipate and address security challenges in the era of quantum supremacy. This abstract offers an impartial overview of our study, adhering to the prescribed structure and avoiding unwarranted exaggerations. It ensures a concise representation of our contributions, guiding readers to the main text for further exploration. By addressing these issues, we aim to contribute to the ongoing efforts to secure digital communication systems amidst evolving technological landscapes. We believe that our research provides valuable insights for policymakers, industry practitioners, and researchers alike, fostering a proactive approach to cybersecurity in the quantum era.
