Synchronization method for SCA and fault attacks

Abstract

This paper shows how effectiveness of side-channel and fault attacks can be improved for devices running from internal clock sources. Due to frequency instability of internally clocked chips, attacking them was always a great challenge. A significant improvement was achieved by using a frequency injection locking technique via the power supply line of a… (More)
