  • Abstract

    The rapid advancement of quantum computing poses a critical threat to classical cryptographic schemes that secure modern distributed systems. As the deployment of distributed infrastructures—including blockchains, cloud-native applications, and edge networks—continues to grow, there is an urgent need to transition towards quantum-resistant security mechanisms. This paper provides a comprehensive examination of post-quantum cryptographic (PQC) algorithms and their applicability in distributed system architectures. We analyze the impact of quantum threats on key components of distributed systems such as communication protocols, identity management, data integrity, and consensus mechanisms. Furthermore, we evaluate current NIST-standardized PQC algorithms in terms of computational efficiency, scalability, and integration overhead within distributed environments. Challenges in key management, performance trade-offs, and implementation considerations are discussed. Finally, we propose best practices and future directions for secure, quantum-resilient distributed systems.
