Quantum Key Distribution (QKD) promises unprecedented security based on the principles of quantum mechanics. However, practical implementations of QKD systems are susceptible to various side-channel and implementation attacks that can compromise their security. We presents a comprehensive overview of the literature on side channels and implementation attacks on QKD systems, a systematic categorization of different attack vectors and proposed counter measures and analysis of their impact on security. Furthermore, we propose a structured approach for developing standardized tests to evaluate the robustness of QKD systems against these vulnerabilities. Our work aims to bridge the gap between theoretical security and practical implementation, providing a roadmap for future certification of QKD products to be deployed within the European Quantum Communication Infrastructure (EuroQCI).
