Google Plans Post-Quantum Cryptography Transition by 2029

Google has announced its intention to complete the transition to post-quantum cryptography (PQC) by 2029. According to Foresight News, this move aims to address the potential threats posed by future quantum computers to current encryption standards. Google highlighted that quantum computers could significantly undermine existing encryption methods, particularly affecting encryption and digital signatures. The threat to encryption is already evident through attacks such as 'store now, decrypt later,' while digital signatures face future risks that need to be addressed before the deployment of cryptography-related quantum computers (CRQC). In response, Google has adjusted its threat model to prioritize the migration of authentication services to PQC. The company recommends that other engineering teams adopt similar strategies to safeguard against these emerging threats.
