Authorization Recycling in RBAC Systems
/ Qiang Wei ; Jason Crampton ; Konstantin Beznosov ; Matei Ripeanu
[LERSSE-RefConfPaper-2008-026]
As distributed applications increase in size and complexity, traditional authorization mechanisms based on a single policy decision point are increasingly fragile because this decision point represents a single point of failure and a performance bottleneck. [...]
