Secure Distributed Computation in the Exponent
A secure multi-party computation problem deals with computing a function on any input, in a distributed network, ensuring that no more information is revealed to a player in the computation. New protocols are developed for the following interesting variation on a typical problem of secure multi-party computation: Given secrets shared among a group of players, compute the function value of basic computations, such as interpolation, addition, multiplication or inversion, in the exponent. The protocols can be proven robust and secure in standard computation models.
