Be ready for
the quantum future
Design quantum-resistant solutions from the start
Quantum computing is moving out of the lab. It’s moving fast, and with it comes a real threat to the cryptography that protects our digital world. Algorithms like RSA and ECC, which secure encrypted data, trusted firmware, and device identities today, will eventually be at risk. And the danger is already here for many systems through the “harvest now, decrypt later” attack, where sensitive data is stolen now and kept until quantum computers can break it.
ST helps device makers prepare for the quantum era,
so they can build today without worrying about future redesigns
ST helps customers move topost‑quantum cryptography,
so the devices they design today stay secure throughout their full lifecycle and comply with forthcoming regulations.

Why has PQC migration become a priority?
Post-quantum cryptography uses new types of algorithms based on mathematical problems that can resist both classical and quantum attacks. International organizations such as NIST are working to standardize these algorithms so they can coexist with today’s asymmetric methods for key exchange, digital signatures, authentication, and secure communications.
How ST helps protect designs for the quantum era
Crypto-agile solutions
With PQC-ready silicon products and a set of PQC software libraries, ST aims to make the shift to post-quantum cryptography accessible to all. To help device makers build end products that remain resilient in both the pre-quantum and post-quantum eras, ST PQC-ready products use a crypto agile approach, where classical and post-quantum algorithms run together for the same security function.
Explore ST’s growing portfolio of PQC‑ready hardware,
software libraries, and tools designed for real‑world applications.
