چکیده انگلیسی:
Noise in digital circuits has always been minimized to achieve high signal integrity, robust operation and of course high performance. However, for cryptographic applications, increased noise can in fact be beneficial. It can be used effectively to reduce the (cryptographic) Signal-to-Noise (SNR) ratio and to make it harder for an adversary to extract useful information (e.g., secret keys) from the side channel leakage data. A natural question concerns the extent to which intrinsic (internal) noise is required to improve security. In this manuscript, we explore this question and further introduce a methodology to exploit the intrinsic physical noise (i.e., flicker- and thermal-noise) at the secure circuit level. We additionally demonstrate how the values obtained from our methodology translate into relevant cryptographic metrics. Our simulations show that the calculated cryptographic noise values are in close agreement with the noise levels extracted from noisy distributions using transient noise analysis. We finally evaluate (with the proposed methodology) several meaningful parameters which affect the internal noise (and their security extent) such as transistors-sizing and voltage-supply changes.
