Factsheet Post-quantum cryptography

The emergence of quantum computers can have major implications for organizations that process sensitive information. Using a future quantum computer, one can decrypt data that is encrypted with popular cryptographic algorithms. The consequences are, however, even more serious. Encrypted data may already be intercepted, awaiting the possibility to decrypt the data with a future quantum computer. NCSC recommends organizations to draw up a plan of action. This plan of action should describe which measures organizations should take in the years to come, to protect data against the threat of quantum computers.
