Google: Developing a timeline for post-quantum cryptography migration, aiming to complete it by 2029.

Golden Finance reports that on March 26, Google announced a timeline for 2029, planning to complete the migration to post-quantum cryptography (PQC) to ensure data security in the quantum era.

Google stated that last month, they called for strengthening security defenses before future quantum computers can crack existing encryption algorithms. This new schedule is based on a comprehensive assessment of quantum computing hardware development, quantum error correction technology, and quantum resource estimation, to meet the migration needs of the post-quantum cryptography era.

Quantum computers pose a significant threat to current cryptographic standards, especially encryption algorithms and digital signature technologies.

The threats to encryption algorithms already exist, such as “store first, decrypt later” attacks;

Digital signatures face future threats, requiring a transition to post-quantum cryptography before cryptographically capable quantum computers (CRQC) emerge.

Therefore, we have adjusted our threat response model, prioritizing the migration of identity authentication services to post-quantum cryptography — a key step in upgrading cybersecurity and digital signatures. We also recommend that other technical teams adopt the same strategy.
