Star Topological Secure Sum Protocol With Trusted Third Party

Secure Multiparty Computation allows all parties to compute the common result of their individual data without disclosing their data to others party. Secure sum computation is one of the important tools of the Secure Multiparty Computation. In Secure Multiparty Computation lot of reputed researchers give their protocols, researchers show their interest. In this paper we proposed a new secure multi party computation protocol which is combination of both real and ideal model as well as the star topology for providing the highest privacy to the database with the zero percentage of data leakage and also the complexity of this protocol is very lesser as compare to other protocol and this protocol is useful for multi party computation. The complexity of this protocol is O (n).
