Time-based access control

Definition

Temporal access control refers to access control service that restricts granting of authorization based on time. The authorization may be given to a subject for a particular interval or duration of time or based on the temporal characteristics of the objects being accessed. Such a need arises from the fact that a subject’s need to access a resource and the sensitivity (and hence the protection requirement) of the objects being accessed may change with time.

Historical Background

Work related to temporal access control has only a brief history and goes back to early 1990s. In many real-world situations, access to information and resources may have to be restricted based on time as the subject and object characteristics may change and so can the need for the subject to access the object. For example, in a hospital, the head of the hospital may need to grant the permissions related to a part-time doctor only during certain time intervals....
