Computer science Attribute-based access control models and implementation in cloud infrastructure as a service THE UNIVERSITY OF TEXAS AT SAN ANTONIO Ravi SandhuRam Krishnan JinXinRecently, there has been considerable interest in attribute-based access control (ABAC) to overcome the limitations of the ...
To address significant concerns about privacy breaches in private digital assets, access control based on cryptography systems has become the focus of common research. However, existing designs have scalability and efficiency issues, appealing to more investigation in real-world implementation. In response...
The attribute-based access control uses policies instead of roles to grant access. These policies combine a set of claims together. For example, our user must have a specific job title and also be from a specific country and work for a specific company, and be born between x and y date....
76% of organizations detected insider threat activity over the past five years, butonly 30%believed they had the right tools to handle them. The situation is dire, but there’s a dependable solution. It’s called attribute-based access control (ABAC). ...
based approach to attribute based access control (ABAC). This guide discusses potential security risks facing organizations, benefits that may result from the implementation of an ABAC system and the approach that the NCCoE took in developing a reference architecture and build. Included is a dis...
Typically, MLS-based access control implicates Mandatory Access Control (MAC) such as the Bell–LaPadula (BLP) model [4] that uses security labels for both subjects and objects. However, there are several problems with MLS, such as ”sanitization”, ”covert channels”, and “bypass” that ...
is still required to determine which data should be accessed by each role. Furthermore, Role-based Access Control (RBAC) can also allow for concepts such as inheritance so that the manager of a subject has at least the same rights as the subject itself. According to Chiquito (2022), RBAC...

System security and access control are implemented by the traceable and rev- ocable multi-authority ciphertext-policy attribute-based encryption (TR-MA- CPABE). The main contributions of this paper are shown below: 1. Secure storage and access control: This paper achieves secure storage, fine-...
Authorization is about facilitating user access to the right data under the right conditions.One approach is Attribute Based Access Control, or ABAC.
