Przyszłościowe zabezpieczenia przed pojawiającymi się zagrożeniami kwantowymi

Q-Day is the future point when quantum computers will be powerful enough to break standard public-key cryptography, such as RSA and ECC, using Shor's algorithm. Because of this looming threat, NIST has announced that these algorithms will be deprecated by 2030.

In these active campaigns, adversaries stockpile your sensitive, encrypted data today. Their goal is to hoard this data until quantum technology matures enough to break the legacy encryption and reveal the stolen information.

No. Upgrading every internal server is a massive effort, so Cloudflare acts as an immediate compensating control. By routing traffic through our network, you instantly gain post-quantum protection over the public Internet by default, buying you time to upgrade internal systems at your own pace.

While legacy network security vendors struggle with PQC performance overhead, Cloudflare uses a hybrid approach combining classical algorithms with ML-KEM. This architecture actually results in a net performance boost for secure connections over TLS 1.3.

Post-quantum encryption secures data in transit to stop data harvesting today, while post-quantum authentication will prevent forged credentials and unauthorized access after Q-Day. Cloudflare is actively developing post-quantum authentication for its SASE platform by 2028 and full platform by 2029.
