Role-Based Access Control and the Access Control Matrix

ACM SIGOPS Operating Systems Review, 2001
The Access Matrix is a useful model for understanding the behaviour and properties of access control systems. While the matrix is rarely implemented, access control in real systems is usually based on access control mechanisms, such as access control lists or capabilities, that have clear relationships with the matrix model.

TrustAccess: A Trustworthy Secure Ciphertext-Policy and Attribute Hiding Access Control Scheme Based on Blockchain

IEEE Transactions on Vehicular Technology, 2020
Ciphertext-policy attribute-based encryption (CP-ABE) is widely used in fine-grained access control to achieve the secure data sharing. However, most of the existing CP-ABE access control schemes involve intermediary entities, which might suffer from a ...

Personalizing access control by generalizing access control

Proceedings of the 15th ACM symposium on Access control models and technologies, 2010
We address the problem of providing data subjects with self-selected controls on access to their personal information. Existing approaches for this are not always sufficient in terms of offering the degrees of control and scope for individualization of access policies that are needed for personal data protection (and usage).

SBAC: A secure blockchain-based access control framework for information-centric networking

Journal of Network and Computer Applications, 2020
The information-centric networking (ICN) has been proposed to meet the increasing demand for efficient content delivery. However, the in-network caching mechanism of ICN makes it hard to provide data security and privacy for content providers (CPs ...
