CTCDM: A Complete Time Constraint Based Delegation Model

Chunyan Han, Lianzhong Liu, and Zhouyang Li
Abstract—Time-based delegation transfers privileges between users and reduce the work load of administrators. But there are defectives on the researches of time-based delegation model: incomplete time constraints and name space explosion problem of delegation model. To solve these two problems, following researches has been done: firstly, this paper proposes a time constraint policy including time representation and the time state change algorithm; secondly, based on the time constraint policy, this paper puts forward the Complete Time Constraint Based Delegation Model(CTCDM) to solve the name explosion problem from a certain extent.

Index Terms—Time constraint, delegation, model.
