A city plans to encrypt archival tax records that must remain confidential for several decades. Which approach best reflects algorithm agility and emerging quantum awareness?
Select an answer to reveal the explanation.
Short Explanation
Long-lived secrets outlive today's favorite algorithm. Build so you can swap ciphers and keys later—including when post-quantum standards mature—instead of welding one brittle choice into the archive forever.
Full Explanation
Archives with multi-decade confidentiality needs must anticipate algorithm breaks, larger key requirements, and post-quantum migration. Algorithm agility means protocols and key-management designs allow substitution of algorithms and parameters without rewriting the entire storage architecture. Awareness-level quantum risk planning reinforces avoiding permanent lock-in to a single classical algorithm.
