Secure multi-party computation protocol can be realized in many ways, which based on OT construct is a useful realization. We use all but many lossy trapdoor function to design noninteractive chosen m out of n OT. Then, we design multi-party computation protocl based on the new OT. Any two participators of the participants need not execute one out of four OT. We introduce the trust (semi-honest) authority (cloud server), then design noninteractive chosen n − i out of 4(n − i) OT between participants to realize multi-party computation protocl.
