Post-breach data control

RepSec-Q: a post-quantum development direction

RepSec-Q is a development direction extending the optional RepSec framework toward post-quantum resilience. Claims depend on the chosen cryptography.

RepSec-Q is in development. It is not a released product. It extends the direction of the optional RepSec™ protocol framework toward post-quantum resilience.

Why a post-quantum direction

Advances in quantum computing are expected to put pressure on some encryption methods in use today. A commonly discussed risk is "harvest now, decrypt later": encrypted data is stolen now and kept until it can be decrypted.

Encryption alone does not address data that has already been exfiltrated or duplicated. RepSec-Q explores how policy, validation and evidence controls can remain dependable as cryptographic standards change.

Focus areas

  • Maintaining control over compromised or duplicated data through policy and validation
  • Verifiable data authenticity and integrity
  • Evidence to support regulatory and compliance reporting
  • Evidence to support cyber-insurance risk and claims review
  • Long-term data governance as post-quantum cryptography is adopted

Important qualifications

  • RepSec-Q is a development direction, not a launched product.
  • Post-quantum claims depend on the selected cryptography and implementation.
  • Like RepSec, RepSec-Q is optional. PastWipe™ does not depend on it.
