Abstract

Some embodiments are directed to a circuit compiling device for compiling a function into a binary circuit and a function evaluation device for evaluating a function using such a binary circuit. The binary circuit comprises conjunction subcircuits each computing a conjunction of function input bits and XOR subcircuits each computing a function output bit. Each function output bit may be represented as a sum of interpolation terms, the plurality of function input bits and the interpolation terms of the one or more function output bits together forming a plurality of interpolation terms. A conjunction subcircuit computes an interpolation term as a conjunction of two interpolation terms. A XOR subcircuit computes a function output bit as a XOR of interpolation terms. Thereby, the first interpolation term and second interpolation term are also used in XOR subcircuits, hence the binary circuit has a smaller number or likelihood of ineffective faults.
