Dec 8, 2023 · When you Enable Post-Quantum Pre-Shared Key (PPK), the Negotiation Mode default setting is Preferred, which means connections that can't support RFC 8784 fall back using to classical cryptography.

You must configure and activate at least one PQ PPK when you Enable Post-Quantum Pre-Shared Key (PPK) so that the firewall has a PQ PPK to use during IKEv2 negotiation and can support RFC 8784.

This PPK is independent of the preshared key (if any) that the IKEv2 protocol uses to perform authentication (because the preshared key in IKEv2 is not used for any key derivation and thus doesn't protect against quantum computers).

Jan 11, 2021 · RFC 8784 (Mixing Preshared Keys in IKEv2 for Postquantum Security) describes an extension to the IKEv2 protocol to allow it to be resistant to a quantum computer by using preshared keys known as PPKs.

Jan 29, 2024 · The RFC 8784 standard, Mixing Preshared Keys in Internet Key Exchange Protocol Version 2 (IKEv2) for Post-quantum Security, enables you to create IKEv2 VPNs that are resistant to attacks based on quantum computers (QCs) …

The RFC 8784 standard, Mixing Preshared Keys in Internet Key Exchange Protocol Version 2 (IKEv2) for Post-quantum Security, enables you to create IKEv2 VPNs that are resistant to attacks based on quantum computers (QCs) and post-quantum cryptographies (PQCs) today.

RFC 8784 (Mixing Preshared Keys in IKEv2 for Postquantum Security) describes an extension to the IKEv2 protocol to allow it to be resistant to a quantum computer by using preshared keys known as PPKs.

Postquantum Preshared Keys (PPK) are an addition to the IKEv2 protocol to ensure that currently encrypted traffic which is stored is safe against against future quantum computer decryption. A PPK is shared securely out-of-band and is used as an input into the SKEYSEED generation.

This specific PPK is independent of the pre-shared key that the IKEv2 Internet Key Exchange version 2. IKEv2 uses the secure channel established in Phase 1 to negotiate Security Associations on behalf of services such as IPsec.

Jul 25, 2024 · Extension to IKEv2 for mixing preshared keys for post-quantum security defined in [RFC8784] allows today's IPsec traffic to be protected against future quantum computers. The protection is achieved by means of using a Post-quantum Preshared Key (PPK) which is mixed into the session keys calculation.
