Spatio-temporal access control: challenges and applications

The traditional access control models, such as Role-Based Access Control (RBAC) and Bell-LaPadula (BLP), are not suitable for pervasive computing applications which typically lack well-defined security perimeters and where all the entities and ...

In the present computing environment, access control decisions are often based on contextual information like the location of users and objects as well as the time of making an access request. Several variants of Role based Access Control RBAC have ...

With the growing advancement of pervasive computing technologies, we are moving towards an era where spatio-temporal information will be necessary for access control. The use of such information can be used for enhancing the security of an application, ...
