A countermeasure against power analysis attacks for FSR-based stream ciphers
2011 (English)In: Proc. ACM Great Lakes Symp. VLSI GLSVLSI, 2011, 235-240 p.Conference paper (Refereed)
In this paper we analyze the power characteristics of Feedback Shift Registers (FSRs) and their e ect on FSR-based stream ciphers. We introduce a technique to isolate the switching activity of a stream cipher by equalizing the current drawn from the cipher with lower power overhead compared to previously introduced countermeasures. By re-implementing the Grain-80 and the Grain-128 ciphers with the presented approach, we lower their power consumption respectively by 20% and 25% compared to previously proposed countermeasures.
