Multiplicative monotone span program is one of the important tools to realize secure multiparty computation. It is essential to construct multiplicative monotone span programs for secure multiparty computations. For any access structure, the researcher gave a method to construct multiplicative monotone span programs, but its row size became double, and the column size also increased. In this paper, the authors propose a new construction which can get a multiplicative monotone span program with the row size less than double without changing the column size.
