Both cloud flare and google have started running real life tests of some post quantum algaritms by including them in some beater versions of the crome browser. Protocles these systems can be used to prevent hacking or stop users accessing prohibited content. The issues also existquote, on a broader internet wide scale in some countries that keep track of what uses are doing. Network security workers refer to these issues as protical ossification.
Almost everything we do on the Internet is made possible by cryptographic algorithms, which scramble our data to protect our privacy. However, this privacy could be under threat. If quantum computers reach their potential these machines could crack current encryption systems — leaving our online data vulnerable.
To limit the damage of this so called 'Q-day', researchers are racing to develop new cryptographic systems, capable of withstanding a quantum attack.
This is an audio version of our feature: The race to save the Internet from quantum hackers
