NIST has released a new Cybersecurity White Paper (CSWP 39) for public comment, focusing on achieving **crypto agility**—the ability to easily update and replace cryptographic algorithms without disrupting ongoing systems. This is especially important as advances in computing, including the potential development of **quantum computers**, threaten current encryption methods. NIST’s **post-quantum cryptography (PQC) standards** aim to address these future risks by providing more secure algorithms that can resist quantum attacks.
The paper outlines strategies and challenges for making systems more adaptable to future cryptographic changes. It emphasizes the need for **interoperability** and **resiliency** as organizations prepare for transitions to new encryption methods. The public has until April 30, 2025, to provide feedback on the draft. NIST also plans to host a virtual workshop to discuss how different sectors can develop their own strategies for achieving crypto agility.
Keywords: post-quantum cryptography, cryptographic agility, quantum computers
