Secure Multi-Party Computation for statistical computations using virtual parties on a Token Ring Network

A novel Secure Multi-party Computation protocol for statistical computations has been proposed and implemented in this work. The described protocol is an enhanced version of our previous proposal of virtual party protocol. Here the system is implemented using a Token Ring Network. Secure Multi-party Computation is classically defined as a system in which computation which involves data from a number of organizations, is performed. Since each organization want to hide its data from other parties, this type of computation requires special security measures. The paper also describes the application of the protocol for secure banking computations, secure business process out-sourcing computations, secure surveys and other intricate statistical computations.
