1. A method for secure computational outsourcing comprising:

  • determining a first set of actual arguments for an outsourced computation;

    determining a second set of actual arguments for said outsourced computation;

    preparing a first group of disguised arguments corresponding to said first set of actual arguments with a first computer;

    preparing a second group of disguised arguments corresponding to said second set of actual arguments with a second computer;

    outputting said first and second groups of disguised arguments from said first and second computers, respectively, for performance of said outsourced computation;

    receiving said first and second groups of disguised arguments with a third computer;

    performing said outsourced computation with said third computer using said first and second groups of disguised arguments to achieve a result;

    sending said result from said third computer to said first and second computers; and

    receiving said result with said first and second computers.
