SIDE CHANNEL LEAKAGE ASSESSMENT APPARATUS AND METHOD

Netherlands

Overview

A side channel leakage assessment apparatus and method are provided. The apparatus classifies a testing set into a first set comprising a first plaintext and first keys and a second set comprising a second key and second plaintexts. The apparatus measures a tested circuit to obtain first side channel signals corresponding to the first set and second side channel signals corresponding to the second set. The apparatus calculates a first power distribution and a second power distribution based on signal powers of the first side channel signals and the second side channel signals. The apparatus determines that whether the tested circuit has a risk of side channel leakage based on extreme values of the first power distribution and the second power distribution.
