DeepSec 2024 Talk: AI Based Attack on Post Quantum Standard “CRYSTALS Kyber” – Maksim Iavich
In recent years, the field of quantum computing has seen remarkable advancements, prompting concerns about the security of current public key cryptosystems in the development’s event of sufficiently powerful quantum computers. Kyber, a post-quantum encryption technique relying on lattice problem hardness, has recently been standardized. However, despite rigorous testing by the National Institute of Standards and Technology (NIST), recent investigations have revealed the efficacy of Crystals-Kyber attacks and their potential impact in real-world scenarios. Following the publication of the paper “Breaking a Fifth-Order Masked Implementation of CRYSTALS-Kyber by Artificial Intelligence” discussions have emerged regarding the vulnerability of the post-quantum crypto system Kyber. The authors propose a side-channel attack leveraging artificial intelligence, specifically employing a neural network training method known as recursive learning to compromise the system. Our study explores CRYSTALS-Kyber’s susceptibility to side-channel attacks.
