**[Google: Developing Post-Quantum Cryptography Migration Timeline, Targeting Completion by 2029]** According to a report by Jinse Finance, on March 26, Google announced a 2029 timeline to complete the migration to **Post-Quantum Cryptography (PQC)** to ensure data security in the quantum era. Google stated that last month, it had called for building a robust security defense for the quantum era before future quantum computers can break existing encryption algorithms. This new timeline was established after comprehensive consideration of factors such as advancements in quantum computing hardware development, quantum error correction technologies, and resource assessments for quantum factorization, to meet the migration needs of the post-quantum cryptography era. Quantum computers will pose a significant threat to current cryptographic standards, particularly encryption algorithms and digital signature technologies. - Encryption algorithms are already facing threats, such as "store now, decrypt later" attacks. - Digital signatures, on the other hand, face future threats, requiring a transition to post-quantum cryptography before cryptographically relevant quantum computers (CRQCs) emerge. As a result, we have adjusted our threat response model, prioritizing the migration of identity authentication services to post-quantum cryptography—this is a critical step in upgrading cybersecurity and digital signatures. We recommend that other technical teams adopt the same strategy.
