The continuous rise of static power consumption in
modern CMOS technologies has led to the creation of a novel
class of security attacks on cryptographic systems. The latter
exploits the correlation between leakage current and the input
patterns to infer the secret key; it is called leakage power analysis
(LPA). The use power-balanced (m-of-n) logic is a promising
solution that provides an answer to this problem, such circuits
are designed to consume constant amount of power regardless of
data being processed. This work evaluates the security of
cryptographic circuits designed with this technology against the
newly developed LPA. Two forms of LPA are investigated, one is
based on differential power analysis (LDPA) and the other based
on Hamming weight analysis (LHPA). Simulations performed at
90nm CMOS technology reveal that (m-of-n) circuits are totally
resilient to LHPA and have a
