Timeline

  • The first Cryptographically Relevant Quantum Computer (CRQC) is expected around 2040, but may become availabe even before 2035:

“even without large disruptions – we estimate that the conservative end is now at 16 years […] a plethora of new developments in error correction and mitigation as well as hardware […] could accelerate the development to even below a decade.“​1

  • Classical asymmetric algorithms will be
    • Deprecated2 by 2030 for key lenghts providing <112 bits​ of security​3
      • RSA < 3072
      • FF (DSA,DH,MQV) < 3072​
      • EC (DSA,DH,MQV), EdDSA < 256-338​
    • Disallowed2 by 2035 for any key length -​ RSA, ECDSA, EdDSA, (FF/EC)DH, MQV​
  timeline
    2024 : First PQ standards - ML-KEM​, ML-DSA​, SH-DSS
         : CNSA suite 2 -- ML-KEM-1024, ML-DSA-87, SHA(3)-384/512, AES-256​
    2025 : ¿ FN-DSA (FIPS 206)
    2027 : ¿ HQC-KEM (FIPS 207) [NIST IR 8545]​
    2030 : Deprecated - key lenghts providing <112 bits​ of security
    2035 : Disallowed for any key length -​ RSA, ECDSA, EdDSA, (FF/EC)DH, MQV​
    2040 : ¿ First CRQC [^BSI_QCE_v2.1]
