Google has taken a major step in securing online communications against quantum threats by integrating post-quantum encryption into Chrome’s Transport Layer Security (TLS) protocol. The latest version of Chrome now supports a hybrid key exchange mechanism combining classical cryptography with post-quantum algorithms like Kyber.

This move is part of Google’s broader quantum-resilient security strategy, aimed at protecting sensitive internet traffic from future quantum attacks. The transition is expected to be gradual, with initial tests involving a subset of users before full deployment.

Cybersecurity analysts view this as a significant step toward mass adoption of PQC, signaling the need for businesses to assess their cryptographic infrastructure and start preparing for a quantum-resistant future.
