—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.
—Time constraint, delegation, model.
