<p>ST has introduced hardware cryptographic accelerators and associated software libraries for general-purpose and secure MCUs. The need for standardizing Post-Quantum Cryptography (PQC) involves using new techniques based on mathematical problems that are hard for quantum computers to solve. ST's offerings include the Keccak algorithm, a hash algorithm invented by ST, and are available through the X-CUBE-PQC software library for STM32 developers and the SHA-3 hardware accelerator in Stellar automotive microcontrollers. New software libraries and hardware IPs are also provided for secure microcontrollers, targeting Common Criteria and FIPS 140-3, and PQC algorithms like ML-KEM, ML-DSA, and XMSS/LMS.</p>
