Abstract

The static power consumption of modern CMOS devices has become a substantial concern in the context of the side-channel security of cryptographic hardware. Its continuous growth in nanometer-scaled technologies is not only inconvenient for effective low-power designs but does also create a new target for power analysis adversaries. Additionally, it has to be noted that several of the numerous sources of static power dissipation in CMOS circuits exhibit an exponential dependence on environmental factors which a classical power analysis adversary is in control of. These factors include the operating conditions’ temperature and supply voltage. Furthermore, in the case of clock control, the measurement interval can be adjusted arbitrarily. Our experiments on a 150-nm CMOS ASIC reveal that with respect to the signal-to-noise ratio in static power side-channel analyses, stretching the measurement interval decreases the noise exponentially and even more importantly that raising the working temperature increases the signal exponentially. Control over the supply voltage has a far smaller, but still noticeable, positive impact as well. In summary, a static power analysis adversary can physically force a device to leak more information by controlling its operating environment and furthermore measure these leakages with arbitrary precision by modifying the interval length.

7. Dual-rail transition logic: A logic style for counteracting power analysis attacks

Abstract

Abstract: In this paper, a new logic style is proposed to be used in the implementation of cryptographic algorithms. The aim of this approach is to counteract power analysis attacks. The proposed technique is based on the transition signaling. In dual-rail transition logic, one-bit value is transmitted by a transition on the proper signal of a couple of wires. According to this concept, converter units and logic gates are defined; it is proposed to use flip-flops to build DTL alternative parts. Although the usage of flip-flops leads to increase the required area, experimental results show that the power consumption of DTL circuits depends on unpredictable initial state of T-flip-flops. In other words, DTL randomizes the power consumption without using random number/mask generators while its delay time is reasonable in comparison with other logic styles. The difference of mean traces and the simulated attacks show that the power consumption of DTL gates does not correlate with the input/output values. [Copyright &y& Elsevier]
