CRYSTALS-Kyber is one of the public-key algorithms currently recommended by NIST as part of its post-quantum cryptography standardization process.

Researchers have just published a side-channel attack-using power consumption-against an implementation of the algorithm that was supposed to be resistant against that sort of attack.

What makes this work really interesting is that the researchers used a machine-learning model to train the system to exploit the side channel.
