STMicroelectronics (ST), a global semiconductor company, provides strong security in the era of quantum computers.

ST has unveiled a post-quantum cryptography (PQC) solution that can respond to quantum attacks in embedded systems.

Presented at the Embedded World 2025 exhibition and conference in Nuremberg, Germany, the solution is integrated into general-purpose and security microcontrollers.

ST's new products include hardware cryptography accelerators and associated software libraries, providing robust security for the era of quantum computing.

Post-quantum cryptography is a new encryption standard to deal with the threat of quantum computers, and ST has developed a hash algorithm with high resistance using the Keccak algorithm.

ST provides developers of STM32 and Stellar automotive microcontrollers with a SHA-3 hardware accelerator solution via the X-CUBE-PQC software library.

It also provides software libraries and hardware IPs for security microcontrollers, and supports ML-KEM, ML-DSA, and XMSS/LMS PQC algorithms targeting Common Criteria (CC) and FIPS 140-3.

Jacques Pugh, SVP of ST Security Platforms“ST is the first company to offer quantum-resistant capabilities across all product lines, for all customers and at all security levels,” said Jacques Fournier, adding that quantum computers are expected to bring benefits in a wide range of fields, including finance, scientific research, and Earth observation.

ST’s post-quantum cryptographic assets are available immediately, enabling customers to apply quantum resistance to critical security features in their products, such as firmware updates, secure boot, and authentication mechanisms.

ST’s Jacques Fournier will speak at the Embedded World exhibition forum in Nuremberg, Germany, on March 12, 2025. During the event, visitors can see related demos at the ST booth (4A-148) and discuss the latest quantum-resistant algorithms with ST security experts.
