QuSecure and Graphiant: Futureproofing Networking Cybersecurity with Crypto-Agility

Quantum threats are moving from theory to planning cycles. NIST has released initial post-quantum encryption standards, and migration work is underway across regulated industries.

The biggest risk is data capture today, followed by decryption later, once quantum systems reach scale. NIST calls “harvest now, decrypt later” a key driver for early adoption of post-quantum cryptography.

The paper QuSecure and Graphiant: Futureproofing Networking Cybersecurity with Crypto-Agility outlines a path to post-quantum readiness built on two requirements: crypto-agility plus private networking designed for secure data in motion.

Key points covered:

1. Quantum algorithms such as Shor’s algorithm threaten widely used public-key schemes, including RSA.
2. Long-life datasets face unique exposure from “steal now, decrypt later,” with secrecy horizons measured in decades for national, healthcare, and financial data.
3. QuSecure positions centralized control, crypto visibility, and three forms of agility as the practical way to keep pace as standards shift.
4. The integration model keeps key control at the edge. The paper describes Graphiant portal tenancy linked to a PQC key provider, programming edge keystores with PQC-derived keys while preserving Graphiant’s posture of no access to private keys.
