Full Key Extraction of SNOW-V Using ML-Assisted Power SCA

Editor’s notes: Power side-channel analysis (SCA) attack represents a powerful means to leak secret key from a cryptographic hardware. This article demonstrates SCA-based complete secret key recovery for SNOW-V stream cipher, a communication standardization candidate for 5G network, and effectiveness of masking countermeasures. –Swarup Bhunia, University of Florida, USA
