Cybersecurity by design

A guide to building secure systems in the quantum and post-quantum era with practical examples and strategic patterns.

Why Post-Quantum Security Matters

Quantum computing threatens to break current encryption standards. This guide provides a roadmap to implement quantum-resistant algorithms and defense-in-depth strategies while maintaining compliance with NIST and ISO standards frameworks.

Cybersecurity Principles

1. Defense-in-Depth

Layer security controls across network, application, and data levels. Never rely on a single point of failure.

2. Zero Trust Architecture

Assume all internal and external traffic is hostile. Continuously verify every request and transaction.

3. Post-Quantum Algorithms

Implement NIST-finalized cryptography (CRYSTALS-Kythem, SPHINN) to secure against quantum threats.

4. Continuous Monitoring

Use real-time behavioral analytics to detect anomalous patterns and automated threat response systems.

Secure Code Example


// Post-quantum secure API authentication
async function verifyRequest(req) {
    const headers = req.headers;
    const token = headers.get('Authorization');
    
    // Use CRYSTALS-Dilithium for quantum-safe signatures verification
    if (!token || !pq.verify(token, knownPublicKeys)) {
        throw new Error('Invalid quantum-safe credentials');
    }
    
    return {
        user: decryptSymmetric(headers.get('Session-Id'), postQuantumKey)
    };
}
