Post-quantum Cryptography

What is post-quantum cryptography?

Post-quantum cryptography refers to new algorithms that are resistant to attacks by quantum computers. Based on new mathematical foundations, post-quantum algorithms will replace current encryption schemes such as RSA and ECC. Their implementation requires an unprecedented degree of innovation and cooperation between academia and industry.

Quantum computers will have the potential to break today’s public key cryptography standards, posing a significant threat to information security. ST launched a post-quantum cryptography program to support the standardization and development of new algorithms, and secure a seamless transition to new crypto-agile ecosystems.

ST post-quantum cryptography program

ST experts from various technical fields are building the future of post-quantum cryptography with two main goals in mind.

Standardization process

The National Institute of Standards and Technology (NIST) is working together with the industry to pioneer new cryptography standards that will protect data from both quantum and classical threats.
In 2022, NIST selected four quantum-safe algorithms for standardization: CRYSTALS-Kyber, CRYSTALS-Dilithium, FALCON and SPHINCS+—more will follow. Initially developed by ST, Keccak algorithm plays a key role in most future quantum-safe algorithms.

Ensure a smooth and successful migration

Build new application standards
ST is actively contributing to new application standards that will support a mix of quantum-safe and classical algorithms.

Offer crypto-agile products
To keep up with evolving threats and cryptographic standards, ST R&D teams focus on the development of crypto-agile hardware and software products. The goal is to help developers quickly upgrade their solutions.
