Abstract

This chapter provides a concise yet thorough examination of Quantum True Random Number Generators (QTRNGs), focusing on their critical role in generating truly unpredictable and irretrievable random numbers, essential for various security algorithms. The study delves into the foundational principles of QTRNGs, highlighting the physical processes that enable genuine randomness. It also evaluates the security attributes of QTRNGs, discussing potential vulnerabilities and defenses against manipulation and attacks. The chapter concludes by assessing the practical applications and limitations of QTRNGs, offering insights into their current and future relevance in enhancing security in computational systems.
