Recently, the National Institute of Standards and Technology set CRYSTALS-Kyber as post-quantum public key encryption/key encapsulation mechanism standard, and CRYSTALS-Dilithium as post-quantum digital signature standard. These post quantum cryptosystems are also recommended for national security systems. As a result, it is important to identify and analyze the weaknesses and potential information leakage points, so that they can be resolved. In this work, we study the newest side channel attacks based on artificial intelligence models against Kyber and Dilithium, focusing on the specific function attacked. We also examine the artificial intelligence algorithms employed in these attacks and their configurations, discussing which parameters and setting are suitable, and identifying different tools that might be useful.
