The study focuses on the problem of constructing secret sharing schemes realizing disjunctive hierarchical access structures. Two ideal solutions are proposed. The first scheme is almost surely perfect, and the second one, which is an extension of the first scheme, is always perfect. We present the first scheme just to make the extended scheme easier to understand. The schemes are based on simple linear algebra.
