The Equivalent Conversions of the Role-Based Access Control Model [PDF]
CEUR Workshop Proceedings. 2017. Vol. 2081 (Selected Papers of the
VIII All-Russian Scientific and Technical Conference on Secure Information
Technologies, BIT 2017). P. 11-14, 2018 The problems which are important for the effective functioning of an access control policy in a large information system (LIS) are selected. The general concept of a local optimization of a role-based access control (RBAC) model is formulated. The optimization criteria are proposed.

The Next 700 Policy Miners: A Universal Method for Building Policy Miners [PDF]
arXiv, 2019 A myriad of access control policy languages have been and continue to be proposed. The design of policy miners for each such language is a challenging task that has required specialized machine learning and combinatorial algorithms. We present an alternative method, universal access control policy mining (Unicorn).

, 2012 In this paper we propose a trust-aware enhancement of RBAC (TA-RBAC) that takes trustworthiness of users into consideration explicitly before granting access. We assume that each role in the framework is associated with an expression that describe trustworthiness of subjects required to be able to activate the role, and each subject (user) has assigned

Semantic security: specification and enforcement of semantic policies for security-driven collaborations [PDF]
, 2009 Collaborative research can often have demands on finer-grained security that go beyond the authentication-only paradigm as typified by many e-Infrastructure/Grid based solutions.
