Cryptographic Role-Based Access Control, Reconsidered [PDF]
, 2022 A significant shortcoming of traditional access control mechanisms is their heavy reliance on reference monitors. Being single points of failure, monitors need to run in protected mode and have permanent online presence in order to handle all access ...

Argumentation for Access Control [PDF]
, 2005 In this paper we are interested in argument based reasoning for access control, for example in the context of agents negotiating access to resources or web services in virtual organizations. We use a logical framework which contains agents with objectives concerning access to a resource or provision of a service, including security objectives.

Controlling Access to Documents: A Formal Access Control Model [PDF]
, 2006 Current access-control systems for documents suffer from one or more of the following limitations: they are coarse-grained, limited to XML documents, or unable to maintain control over copies of documents once they are released by the system. We present a formal model of a system that overcomes all of these restrictions.
