1. A method of initiating performance of a computation on at least one untrusted computer, the method comprising: partitioning the computation into a plurality of computational units that are combinable to generate a result for the computation; generating at least one distractive computational unit; initiating execution of both the at least one distractive computational unit and at least one of the plurality of computational units on the untrusted computer to inhibit reconstitution of the computation by an untrusted party.
