摘要

As Large and Fault-Tolerant (LFT) quantum computers preset in emerging, classical Digital Signature (DS) algorithms used in DS-enabled applications hosted on cloud Virtual Machines (VMs) are increasingly vulnerable to security threats. To safeguard these critical applications in the forthcoming quantum era, it is essential to explore Quantum-safe Digital Signature (QSDS) algorithms across various cloud VMs. To address this challenge, we propose a comprehensive feasibility framework that evaluates hardware and network capabilities for deploying the National Institute of Standards and Technology (NIST)’s Round Three QSDS algorithms. This framework specifically targets DS-enabled applications across diverse cloud VMs. Hence, we equip decision-makers with actionable insights to select the most suitable cloud VM for effective QSDS deployment, ensuring the resilience of these applications against the evolving threats posed by quantum advancements.
