How to distribute a secret key information to n authorized departments(denoted as: S1, S2Sn, respectively).For every autherized department Si(#em/em#=1, 2,, n), there are qi authorized persons,and every authorized person has the same secret key information as that of any other authorized persons in the same authoried department.The secret key information can be reconstrueted Completely from the secret key information of any k authorized persons， if there is at least one authorized person included for every authorized department.But other cases,the secret key information cannot be reconstructed completely.In this paper,based on the algebraic semigroup theory,a secret key sharing scheme is proposed,which can satisfy the demand.
