Professor of Tsinghua University: resist the threat of quantum computing, starting with anti-quantum cryptography

Anti-quantum cryptography (also known as post-quantum cryptography, PQC) is a new generation of cryptographic algorithms that can resist attacks on existing cryptographic algorithms by quantum computers. If modern cryptography is the cornerstone of cyberspace security, then anti-quantum cryptography is the security cornerstone of the future digital economy. In this issue of digital security in the future
