Secure Multi-party Computation

Abstract

SMC(Secure Multi-party Computation)mainly addresses the problem of cooperation within the distrustful partners,SMC requires the independence assurance of inputs and computation correctness,and meanwhile shouldn't leak any input to other partners. SMC could be widely used in internet ballot and internet auction. This paper analyzes the key technologies,including secure protocols,bit commitment,oblivious transfer,and zero-knowledge proof. Finally,the paper describes the applications of SMC,and these are significant in theory and practice.
