The platform successfully extracts keys from masked AES modules.

SPERO dataset facilitates future research in side-channel attack analysis.

Abstract

Cryptosystem implementations often disclose information regarding a secret key due to correlations with side channels such as power consumption, timing variations, and electromagnetic emissions. Since power and EM channels can leak distinct information, the combination of EM and power channels could increase side-channel attack efficiency. In this paper, we develop a miniature dual-channel side-channel detection platform, named RASCv3 to successfully extract subkeys from both unmasked and masked AES modules. For the unmasked AES, we combine EM and power channels by using mutual information to extract the secret key in real-time mode and the experiment result shows that less measurements-to-disclosure (MTD) is used than the last version (RASCv2). Further, we adopt RASCv3 to collect EM/Power traces from the masked AES module and successfully extract the secret key from the masked AES module in fewer power/EM/dual channel traces. In the end, we generate an ASCAD format dataset named SPERO, which consists of EM and power traces collected simultaneously during unmasked/masked AES module doing encryption and upload to the community for future use.
