Summary of Access Control Mechanisms for the IoT based on HyBAC.
| Ref. | Purposes | Key Contribution | Implementation |
|---|---|---|---|
| [75] | Combining RBAC and ABAC models for IoT access control. | Proposes an Attribute-Based and Role-Based Hybrid Access Control (ARBHAC) model for the large-scale dynamics users to improve policy management. | No |
| [76] | Combining RBAC and ABAC models to address the issues of scalability and flexibility in IoT access control to a fine-grained level. | Proposes an access control model for the IoT combining with properties of both RBAC and ABAC models. | No |
| [77] | Combining RBAC and ABAC models for IoT access control. | Presents a Policy RC-ABAC (Role-Centric ABAC) model to address the need for fine-grained and flexible access control for IoT systems. | No |
| [78] | Combining RBAC and ABAC models for access control in autonomous vehicles. | Proposes an access control architecture called Hybrid Access Control (HAC) that focuses on the secure localization of IoT-enabled smart vehicles. | No |
| [79] | Combining RBAC, ABAC, and CapBAC models for light-weight access control at edge IoT devices. | Attributes are employed for role membership assignment and access control permission evaluation. The membership of roles grants capabilities (i.e., access tokens) for specific access to a resource. | Yes |
| [80] | Building an access control model for cloud-based IoT services. | Proposes an access control architecture for IoT-enabled smart healthcare systems to handle a big amount of data without human intervention. | No |
| [81] | Combining trust and ABAC models for IoT access control. | Develops a Trust-ABAC model for fine-grained access control in IoT systems based on provided attributes and trust value of a service requesting entity. | Yes |
| [82] | Combining the notion of trust (i.e. trust value) and ABAC model for IoT access control. | Proposes a distributed, and flexible access control model for IoT using trust attributes that are based on an entity’s trust evaluation. | No |
| [83] | Combining trust and RBAC models for IoT access control. | Develops a model for mobile cloud-based IoT infrastructure to provide fine-grained access control for complex IoT systems that depends upon a highly dynamic context. | Yes |
