Post-Quantum Security Consulting

As cyber threats evolve and quantum computing becomes a practical reality, today’s cryptographic standards no longer guarantee long‑term protection. Beyond encryption, core authentication and key‑exchange mechanisms will also require modernization to remain secure in a post-quantum environment.

As part of our IDEMIA Sphere Cybersecurity offer, we provide expert guidance to help leaders assess their cryptographic exposure, prioritize migration efforts, and implement post‑quantum–ready architectures that remain secure, efficient, and aligned with emerging standards.

Cryptographic risk assessment and quantum-readiness

We begin by conducting a thorough evaluation of your existing cryptographic stack, including protocols, key management, trust models, and algorithm choices. Instead of looking only at today’s threats, we assess exposure over time, taking into account how both classical and quantum cryptanalysis may evolve.

This analysis highlights:

• vulnerabilities in current architectures,
• risks likely to emerge as quantum capabilities mature

Long‑term secure cryptographic design

Based on your environment and constraints, we help redesign or evolve your cryptographic architecture to ensure durable security. Our approach balances strong protection with real‑world requirements such as performance, operational constraints, hardware limitations, and deployment complexity.

We focus on creating architectures that are not only secure but also practical to implement and maintain at scale.

Post-Quantum migration and implementation support

Our team defines a migration roadmap tailored to your architecture, selecting suitable post‑quantum algorithms, designing crypto‑agile mechanisms, and assessing the impact of different attack scenarios to guide prioritization.

Once the strategy is set, we support its implementation across your platforms: cloud services, embedded systems, secure elements, and HSMs. This includes integrating new primitives, adapting key management workflows, validating performance, and ensuring resistance to implementation‑level attacks.

Our support typically covers:

• introducing post‑quantum and hybrid modes into existing systems
• ensuring smooth integration with IDEMIA Sphere CryptoLib and IDEMIA Sphere HSM
• mitigating operational and performance impacts during the transition

This combined approach ensures a secure, efficient, and sustainable migration to quantum‑safe cryptography.

Cryptographic security and performance optimization

When required, we conduct targeted studies to improve both the security and efficiency of your cryptographic operations. This may involve protocol hardening, evaluating alternative constructions, or tuning performance-critical components.

Our goal is to ensure your cryptographic system remains reliable, optimized, and aligned with your long-term security strategy.
