Power analysis attack on Kyber
Alexandre Karlov and Natacha Linard de Guertechin
Abstract
This paper describes a practical side-channel power analysis on CRYSTALS-Kyber key-encapsulation mechanism. In particular, we analyse the polynomial multiplication in the decapsulation phase to recover the secret key in a semi-static setting. The power analysis attack was performed against the KYBER512 implementation from pqm4 running on STM32F3 M4-cortex CPU.
