This executive briefing explains why high-quality randomness—known as entropy—must be treated as a foundational security dependency as organizations prepare for the quantum era. While most quantum-readiness efforts focus on migrating to post-quantum cryptography (PQC), this briefing highlights a critical but often overlooked risk: weaknesses in entropy can silently undermine today’s encryption, reducing security long before large-scale quantum computers emerge.
Written for senior leaders and decision-makers, the briefing translates technical findings into clear business risks, governance implications, and actionable steps. It outlines why entropy quality affects the real-world strength of encryption such as AES, how entropy failures impact cloud, IoT, and 5G environments, and what executives should do now to integrate entropy visibility, governance, and mitigation into enterprise risk management and cryptographic migration planning. For a detailed technical analysis of entropy quality, AES-128 security, and quantum-era, its implications, including real-world examples and mitigation strategies. Please see the detailed white paper, Entropy Quality and the Security of AES-128 in Classical and Quantum Contexts.
