Protecting Circuits from Computationally Bounded and Noisy Leakage [PDF]
SIAM Journal on Computing, 2014 Physical computational devices leak side-channel information that may, and often does, reveal secret internal states. We present a general transformation that compiles any circuit into a circuit with the same functionality but resilience against well-defined classes of leakage.
