Abstract(in English) In this paper, a new construction scheme of secret sharing system with classified membership has been proposed. It is possible to recover the secret information only when the member of pieces gathered in a class and the number of such classes become more than or equal to a predetermined threshold value. The mechanism of system is to generate each member's piece using a new one-way hash function involving ID-vectors derived from each member's ID and his belonging class. Finally, suitable setting of parameters in our system will make possible to construct secret sharing system well-fitted to some real problems.
