The shift to post-quantum cryptography (PQC) is already underway. For embedded and IoT devices, PQC is crucial for long-term security, yet implementing it on resource-constrained hardware with larger keys and new cryptographic primitives is challenging. Even mathematically sound algorithms can leak information through side channels or behave unexpectedly under fault conditions. As industry standards mature and regulatory requirements rise across sectors such as payments, automotive, and critical infrastructure, organizations need to validate their PQC implementations now to ensure security and interoperability, as well as timely market access.

Keysight helps teams deploy PQC securely and efficiently with dedicated testing solutions, compliance expertise, and practical integration guidance. By validating implementations from design to deployment, we help reduce risk, support certification, and enable secure, future-ready products.

Frequently Asked Questions

Today’s quantum computers are still too limited to break modern cryptographic algorithms like RSA and ECC, and experts estimate it may take 15–20 years before cryptographically relevant quantum computers (CRQCs) are available. That sounds distant, but the risk is already present: attackers can capture encrypted data now and decrypt it later once CRQCs become available – a risk known as “harvest now, decrypt later”.

Systems that must remain secure for many years, such as those in government, defense, and critical infrastructure, are especially exposed and need quantum-safe protection well before CRQCs arrive. Consumer and short-lived commercial systems may face a lower immediate risk, but they are not immune to future quantum attacks.

The transition to post-quantum cryptography is moving from “optional” to expected as global standards and compliance timelines take shape. Government and high-assurance contracts are beginning to require quantum-safe roadmaps or concrete PQC adoption plans.

To maintain security, interoperability, and market access, organizations need to understand upcoming requirements, select appropriate quantum-safe algorithms, and plan for compliant, secure implementations rather than treating PQC as a future add-on.

Standardized PQC algorithms may be secure on paper, but their implementations can still be vulnerable to physical attacks. When PQC runs on real devices, it can leak information through side channels (e.g., power, timing, EM) or behave unexpectedly under fault injection.

By testing implementation security using methods such as Side-Channel Analysis (SCA) and Fault Injection (FI), you can uncover issues like key-dependent leakage or fault-based key recovery and design effective countermeasures.

Yes, especially if your products are long-lived, hard to update, or subject to strict regulation. Updating firmware, secure elements, or cryptographic modules after deployment is costly and sometimes impractical, particularly for embedded and remote systems. Designs that are not built with quantum-safe cryptography in mind may require full hardware replacement or complex patching later.

At the same time, testing practices must evolve: traditional approaches like classical TVLA were not designed for PQC’s larger states and more complex operations. Starting now gives you time to adapt your evaluation methods, plan migrations, and integrate PQC and its implementation security into your normal development lifecycle, instead of scrambling to retrofit when requirements become mandatory.

Build Your Next-Gen Device Security Test Lab

Validating post-quantum cryptography (PQC) on embedded systems requires both a robust hardware security testing setup and advanced analysis tools. Keysight provides a comprehensive portfolio to help you validate and harden your embedded system against side-channel and fault-injection attacks — from pre-silicon to post-silicon.

Our solutions support testing across a wide range of form factors and abstraction levels, from pure hardware to low-level software such as firmware and secure boot.
