What does this research mean for the field?

There is a structural mismatch between long data confidentiality obligations and immature post-quantum migration readiness, leaving data with multi-decade confidentiality requirements already exposed to the harvest-now-decrypt-later threat. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Map documented data-confidentiality lifetimes across data categories against post-quantum migration readiness across custodian sectors, using Mosca's inequality to evaluate exposure to harvest-now-decrypt-later threats.

Scoping review finds a structural mismatch between long data-confidentiality requirements and post-quantum migration readiness, indicating immediate exposure under harvest-now-decrypt-later threats.

Key Points

Map documented data-confidentiality lifetimes across data categories against post-quantum migration readiness across custodian sectors, using Mosca's inequality to evaluate exposure to harvest-now-decrypt-later threats.
Followed the Arksey and O'Malley framework, Joanna Briggs Institute guidance, and PRISMA Extension for Scoping Reviews.
Synthesized evidence from N=42 sources covering peer-reviewed literature, standards bodies, government documents, and labeled grey literature.
Documented confidentiality lifetimes span decades or are effectively perpetual for national security, health, genomic, biometric, and legal records, and years to decades for financial data.
Migration readiness documentation is uneven across sectors, being most developed in defense and government, partial in finance and telecommunications, and largely absent in healthcare, genomics, and legal sectors.
Application of Mosca's inequality demonstrates that categories with multi-decade or indefinite confidentiality needs are already actively exposed to harvest-now-decrypt-later threats due to the projected arrival horizons of quantum computers.
