ABSTRACT
In this paper, we propose a secret sharing scheme with the property of access structures in a hierarchy. We employ the concept of admission tickets to delegate the access right from ancestors to their descendants. Each participant group has an authorized access structure and each access structure has its own secret key. The presented scheme is based on general hierarchies, and may be more suitable for real applications.
INDEX TERMS
document management, secret sharing, access structure, hierarchical access control, delegation and agreement
