后量子加密
什么是后量子加密？
后量子加密 (PQC) 是指一种能够抵御量子计算机攻击的新型算法。后量子算法以全新数学难题为基础，未来将取代RSA和ECC等现行加密方案。实现此类算法，需要依靠深度创新以及学术界与工业界之间的密切合作。
未来，量子计算机将有可能打破今天的公钥加密标准，对信息安全构成重大威胁。为提前应对这种威胁，意法半导体启动了后量子加密计划，为新算法的开发和标准化提供支持，并确保平稳过渡到新的敏捷加密生态系统。

意法半导体各个技术领域的专家正以两大目标为导向，努力开发面向未来的后量子加密技术。
标准化流程
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 August 2024, NIST released three new cryptographic standards: FIPS-203 (ML-KEM) for key encapsulation, FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA) for digital signature. Initially developed by ST, the Keccak algorithm plays a key role in these newly standardized quantum-safe algorithms. These three algorithms complement the LMS and XMSS (SP800-208) algorithms standardized in 2020.
确保顺利且平稳的迁移
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.
