NSA CSfC Symmetric Key Annex 3.0.0 Adds Quantum-Resistant Pre-Shared Keys for Classified Solutions

NSA's Commercial Solutions for Classified program published Symmetric Key Annex 3.0.0, adding quantum-resistant pre-shared keys for classified solutions. It formalizes symmetric key methods, including RFC 8784 style pre-shared keys in IPsec, as an accepted path to quantum resistance for high assurance networks.

Why this matters for your infrastructure

Every advance in quantum computing shortens the window for migrating long lived infrastructure off quantum-vulnerable encryption, and data captured today can be decrypted later. Fabric Networks helps energy, government, telecom and community networks move to quantum-safe encryption on their own timeline, not an adversary's.
