  • •NCSC recommends immediate migration to TLS 1.3 for quantum resilience.
  • •Hybrid and pure PQC cipher configurations are now advised for TLS.
  • •High priority migration activities should be completed by 2031.

The NCSC has released updated guidance on using TLS to incorporate post-quantum cryptography (PQC) configurations. This update follows the IETF's RFC 10024 publication, which standardizes hybrid key agreement mechanisms for TLS 1.3. Organizations using TLS 1.2 or older versions are urged to transition to TLS 1.3 to enhance security against quantum threats. The guidance emphasizes the importance of both hybrid and pure PQC cipher choices, with a recommendation for immediate migration to TLS 1.3. The NCSC advises that protecting data confidentiality in transit is a high priority, with a migration timeline set for completion by 2031. Stable pure PQC options are already available in major libraries, despite some delays in final RFC publication. The NCSC will continue to update its technical guidance as PQC support evolves.
