Post-Quantum Cryptography (PQC)

The Software-Based Shield to Withstand Quantum Attacks

Post-Quantum Cryptography (PQC), also known as quantum-resistant cryptography, refers to a new class of cryptographic algorithms designed to be secure against attacks from both classical and quantum computers.

PQC is a software and protocol upgrade. It relies on new, complex mathematical problems that are believed to be exceptionally difficult for a quantum computer to solve, even with its immense power.

Key Business Benefits

Software-Only Deployment

No new hardware required; upgrade existing systems via patches, libraries, or protocol updates.

NIST-Approved Security

Leverage algorithms vetted by global cryptographic experts for quantum resistance.

Minimal Performance Impact

Modern PQC implementations achieve wire-speed encryption on standard processors (e.g., Intel Xeon).

Crypto-Agility

Easily swap algorithms as standards evolve, avoiding vendor lock-in.

Symmetric Key Agreement Solution

Traditional key exchange methods (Diffie-Hellman, RSA) are broken by quantum computers.

Our Symmetric Key Agreement Platform provides a quantum-safe alternative:

How it works

Endpoints dynamically agree on symmetric encryption keys without transmitting key material over the network. This eliminates the risk of key interception .

THE PROBLEM PQC SOLVES:

THE "HARVEST NOW, DECRYPT LATER" ATTACK

Today

Adversaries are intercepting and storing encrypted data (e.g., state secrets, intellectual property, health records).​

They Assume

That in <10 years, a powerful quantum computer will be available.​

The Attack

They will then use that quantum computer to break the classical encryption (like RSA or ECC) used to protect this stored data.​

The Result

Secrets from today are compromised in the future.

  2. IPSec/MACSec VPNs & SD-WAN

Cloud-First & Globally Scalable

Arqit’s Symmetric Key Agreement (SKA) platform delivers quantum-safe security over any network, including the public internet and cloud environments, without the need for dedicated fiber.

Simplified Integration

The lightweight NetworkSecure agent integrates seamlessly with major network vendors like Fortinet, enabling you to harden existing IPsec VPNs and TLS connections against the quantum threat with minimal overhead.

No Key Distribution

The unique "key agreement" model means symmetric keys are created at endpoints, eliminating the risk associated with transmitting keys.

What is PQC?

Post-Quantum Cryptography (PQC), also known as quantum-resistant cryptography, refers to a new class of cryptographic algorithms designed to be secure against attacks from both classical and quantum computers.

PQC is a software and protocol upgrade. It relies on new, complex mathematical problems that are believed to be exceptionally difficult for a quantum computer to solve, even with its immense power.

The U.S. National Institute of Standards and Technology (NIST) has led a global, transparent multi-year process to select and standardize PQC algorithms (e.g., CRYSTALS-Kyber for key exchange, CRYSTALS-Dilithium for signatures). This provides a trusted, vetted foundation.
