Role-based access control associates roles with privileges and users with roles. Changes to these associations are infrequent and explicit. This may not reflect business requirements. Access to an object should not only be based on the identity of the object and the user, but also on the actual task that must be performed, i.e. the context of the work to be done. Context-sensitive access contro...

In this paper, we present an access control scheme for PIM-SM multicast domain. In order to avoid the overhead of digital signature algorithm, the proposed solution makes use of the Rendezvous Point to collect keys and implement a distributed shared-key based multicast access control system. As it supplies efficient host access control in PIM-SM domain, we name this scheme PIMac. Compared with ...

Role-based access control is an important access control method for securing computer systems. A role-based access control policy can be implemented incorrectly due to various reasons, such as programming errors. Defects in the implementation may lead to unauthorized access and security breaches. To reveal access control defects, this paper presents a model-based approach to automated generatio...
