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.

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.
