Post-quantum Readiness for Long-Retention Public Records
Quantum computing introduces a time-shifted risk for long-retention public records: data encrypted today can be copied now and decrypted later, once quantum capabilities mature. For governments and regulated organizations, this changes how confidentiality, authenticity, and long-term evidentiary trust must be planned. In this article, Letro outlines: 🔹Why long-retention public records face a distinct post-quantum risk
🔹What current hashtag#standards and government guidance (hashtag#NIST, hashtag#CISA, hashtag#UK NCSC) actually require
🔹A practical, phased roadmap for assessing exposure and planning migration
