In this paper, we propose a secret sharing scheme withthe property of access structures in a hierarchy. Weemploy the concept of admission tickets to delegate theaccess right from ancestors to their descendants. Eachparticipant group has an authorized access structure andeach access structure has its own secret key. Thepresented scheme is based on general hierarchies, andmay be more suitable for real applications.
