Abstract
A first circuit representation of a given function is obtained at a first processing device. The given function comprises at least two computer programming switch statement clauses. A second circuit representation is generated at the first processing device from the first circuit representation wherein the at least two computer programming switch statement clauses are respectively represented by at least two tree circuits that are embedded in the second circuit representation such that the second circuit representation is characterized by a given cost (e.g., a minimum cost). The second circuit representation is encrypted at the first processing device, and sent to a second processing device for secure evaluation of the given function by the second processing device.
