In computer security, lattice-based access control ( LBAC) is a complex access control model based on the interaction between any combination of objects (such as resources, computers, and applications) and subjects (such as individuals, groups or organizations). In this type of label-based mandatory access control ...
Attribute-based access control.

Basic access control (BAC) is a mechanism specified to ensure only authorized parties [1] can wirelessly read personal information from passports with an RFID chip. It uses data such as the passport number, date of birth and expiration date to negotiate a session key. This key can then be used to encrypt the communication between the passport's ...
