Security analysis for temporal role based access control [PDF]
, 2014 Providing restrictive and secure access to resources is a challenging and socially important problem. Among the many formal security models, Role Based Access Control (RBAC) has become the norm in many of today's organizations for enforcing security. For

A Model-driven Role-based Access Control for SQL Databases
Complex Systems Informatics and Modeling Quarterly, 2015 Nowadays security has become an important aspect in information systems engineering. A mainstream method for information system security is Role-based Access Control (RBAC), which restricts system access to authorised users.

Traffic Prediction and Random Access Control Optimization: Learning and Non-learning based Approaches [PDF]
arXiv, 2020 Random access schemes in modern wireless communications are generally based on the framed-ALOHA (f-ALOHA), which can be optimized by flexibly organizing devices' transmission and re-transmission. However, this optimization is generally intractable due to the lack of information about complex traffic generation statistics and the occurrence of the ...

Role-Based Access Controls [PDF]
15th National Computer Security Conference, Baltimore, MD. October
13-16, 1992, 2009 While Mandatory Access Controls (MAC) are appropriate for multilevel secure military applications, Discretionary Access Controls (DAC) are often perceived as meeting the security processing needs of industry and civilian government. This paper argues that reliance on DAC as the principal method of access control is unfounded and inappropriate for many ...
