The rapid development of quantum computing poses a significant threat to traditional cryptographic systems (such as RSA and Elliptic Curve Cryptography). Although practical quantum computers capable of breaking classical cryptographic systems (CRQC) have not yet emerged, the "harvest now, decrypt later" attack model exposes existing encrypted data to long-term risks. Gartner predicts that quantum computing will fully compromise classical public-key cryptography between 2033 and 2035, making the accelerated deployment of Post-Quantum Cryptography (PQC) an urgent necessity.

Post-Quantum Cryptography refers to new encryption algorithms designed to resist attacks from quantum computers. Currently, standards organizations, governments, and industries are actively promoting the development of related standards, legislation, and research practices. Tencent Cloud has also initiated preliminary research and planning for post-quantum migration since the end of 2024.

This platform focuses on the latest updates in post-quantum migration, aiming to provide intelligence support for the industry and collaboratively build a quantum-secure cyberspace.
