Bug ID 1517557: Hybrid X25519_Kyber768 Post Quantum Cryptography Support

Last Modified: Feb 28, 2025

Affected Product(s):
BIG-IP LTM(all modules)

Fixed In:
17.5.0

Opened: Feb 13, 2024

Severity: 3-Major

Symptoms

Today's cryptography is entirely dependent on prime numbers factorization and discrete logarithms and there are quantum algorithms that efficiently factor the prime number and compute the discrete logarithms. But it requires Quantum computers.

Impact

Harvest now, decrypt later, also known as store now, decrypt later or retrospective decryption, is a surveillance strategy that relies on the acquisition and long-term storage of currently unreadable encrypted data awaiting possible breakthroughs in decryption technology that would render it readable in the future.

Conditions

Handshakes that use non-PQC (Post-Quantum Cryptography) curves.

Workaround

NA

Fix Information

New DH Curve introduced X25519Kyber768 with tls1.3 handshake which protects post-quantum crypto attacks.

Behavior Change
