No, AI did not break post-quantum cryptography

This post clarifies that the Kyber post-quantum encryption algorithm is not broken, despite recent news coverage. It explains that AI has been used for over a decade in side-channel attacks and details how machine learning, particularly deep learning, can be effective in extracting leaked information from power traces. The post also discusses countermeasures like masking and the limitations of AI-based side-channel attacks, emphasizing that while powerful, they are not a magic bullet and carefully implemented countermeasures remain effective. It highlights that the paper discussed does not break Kyber but rather uses AI to aid in cryptanalysis.
