A framework for decentralized access control
2007
Proceedings of the 2nd ACM symposium on Information, computer and communications security - ASIACCS '07
Preserved Fulltext
We present a framework for decentralized authorization for physical access control, using smart cards, where access to individual rooms is guarded by context-dependent policies that are dynamically evaluated ...
The benefit of this approach lies in resolving authorizations in a decentralized manner in situations where the solution needs to scale with increasing number of users. ...
DECENTRALIZED ACCESS CONTROL FRAMEWORK -OVERVIEW The proposed system framework for physical access control is shown in Figure 1 . We refer to it as Decentralized Access Control (DAC) framework. ...
