1. Towards a Location-Aware Role-Based Access Control Model
Gui Hwan Hwang

2. Motivation wireless networks, sensor and mobile devices increase
- location is an important component of access control
computer containing top secret information should be placed in a designated area.
In military, control or fire missile from specific locations only
Traditional access control cannot provide such location-based access model

3. Approach
Based on RBAC, propose one such formal model that is suitable for commercial applications.
How RBAC can be extended to incorporate the concept of location.
- the different components in RBAC are related with location
- location impacts these different components.
How information can be used to determine whether a user has access to a given object.
