Abstract
Delegation is essential to the flexibility and scalability of trust management systems. But unrestricted delegation may result in privilege proliferation and breach the privacy of information systems. The delegation models of existing trust management systems can not avoid privilege transition, and being lack of effective constraints on delegation propagation, which may easily lead to privilege proliferation. In this paper, we propose a generalized constrained delegation model (GCDM), which uses typed privileges to control potential privilege transition, and restricts the propagation scope of delegation trees by a novel delegation constraint mechanism named spacial constraints. This paper also designs a rule-based trust management language named REAL05 to express the policies and semantics for GCDM. REAL05 supports flexible delegation policies while can control the potential privilege proliferation in subsequent delegations. Comprehensive samples and simulation results show that our approach is more controllable and practical.
