Transition Planning
Migration Strategy
Detailed procedures for transitioning cryptographic systems to quantum-resistant algorithms while maintaining operational continuity and backward compatibility.
Re-encryption of Stored Data
Incrementally decrypt data protected with classical algorithms and re-encrypt using hybrid encryption scheme during off-peak hours.
Complexity:High
Risk:Medium
Large datasets at restKey Migration (Re-wrapping)
Re-wrap existing DEKs with new hybrid KEKs. Bulk data remains untouched while key protection is upgraded to quantum-resistant standard.
Complexity:Medium
Risk:Low
Systems with key hierarchyGateway Intermediaries
Deploy proxy gateways that terminate legacy protocols and establish PQC-secured connections, acting as cryptographic translators.
Complexity:Medium
Risk:Low
Legacy systems that cannot be upgraded
