The paper proposes efficient solutions to two long standing open problems related to secret sharing schemes in multilevel (or hierarchical) and compartmented access structures. The secret sharing scheme in multilevel access structures uses a sequence of related Shamir threshold schemes with overlapping shares and the secret. The secret sharing scheme in compartmented access structures applies Shamir schemes first to recover partial secrets and second to combine them into the requested secret. Both schemes described in the paper are ideal and perfect.
