With the advancement of technology, smart security chip products have evolved from the most common forms like bank cards and telecom cards into various other formats, now integrated into mobile phones, smart home devices, consumer electronics, smart devices, and automobiles. These chips protect the security of identities and transactions through secure encryption algorithms and programs. However, the rapid development of quantum computing technology has introduced new challenges. Some previously considered safe algorithms, such as RSA and ECC, have been proven vulnerable to quantum computers. As a result, industries with high-security demands are paying close attention to research on post-quantum cryptography (PQC). 【Background of the Development of Quantum Technology】 On August 13, the U.S. National Institute of Standards and Technology (NIST) officially released the world’s first three post-quantum cryptography (PQC) standards, with a fourth algorithm standard scheduled for official release by the end of this year. Among the three PQC encryption algorithms published,…
