“…Maw et al [6], [7] proposed an Adaptive Access Control (A2C) model with privilege overriding and behaviour monitoring to provide fine-grained access control for medical data in WSNs. This model has a similar structure to BTG-RBAC [1] but the main difference is that no human effort is needed to override rules and policies because of an introduction of the users' behaviour trust model, and the prevention and detection mechanism.…”

Wireless Sensor Networks (WSNs) have recently attracted a lot of attention in the research community because it is easy to deploy them in the physical environment and collect and disseminate environmental data from them. The collected data from sensor nodes can vary based on what kind of application is used for WSNs. Data confidentiality and access control to that collected data are the most challenging issues in WSNs because the users are able to access data from the different location via ad-hoc manner. Access control is one of the critical requirements to prevent unauthorised access from users. The current access control models in information systems cannot be applied straightforwardly because of some limitations namely limited energy, resource and memory, and low computation capability. Based on the requirements of WSNs, we proposed the Break-The-Glass Access Control (BTG-AC) model which is the modified and redesigned version of Break-The-Glass Role-Based Access Control (BTG-RBAC) model. The several changes within the access control engine are made in BTG-RBAC to apply and fit in WSNs. We developed the BTG-AC model in Ponder2 package. Also a medical scenario was developed to evaluate the BTG-AC model for medical data in WSNs. In this paper, detail design, implementation phase, evaluation result and policies evaluation for the BTG-AC model are presented. Based on the evaluation result, the BTG-AC model can be used in WSNs after several modifications have been made under Ponder2 Package

“…Htoo et al [45,46] proposed an adaptive access control (A2C) model with privilege overriding and behaviour monitoring to provide fine-grained access control for medical data in WSNs. A2C incorporates the concept of possibility-with-override and a user behaviour trust model into WSNs for hard-to-define and unanticipated situations.…”

“…The overview diagram of the distributed network model can be seen in Figure 6. Based on the above discussion, most of the access control models in WSNs use the centralised approach apart from DFAC [41] and A2C [45], which use the distributed approach. However, the network models are quite similar for all the access control models.…”

“…ABE-based encryption is popular relative to other public key encryption methods because of its highly promising approach to realize scalability and fine-grained access control. The ABE method is used in the FDAC [29], DFAC [41], DFG-AC [43] and A2C [45] models for data encryption, as well as for data access control. Data in the sensor nodes are encrypted using attributes and keys from the trusted authorities.…”

This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution license (http://creativecommons.org/licenses/by/3.0/)Wireless sensor networks (WSNs) have attracted considerable interest in the research community, because of their wide range of applications. However, due to the distributed nature of WSNs and their deployment in remote areas, these networks are vulnerable to numerous security threats that can adversely affect their proper functioning. Resource constraints in sensor nodes mean that security mechanisms with a large overhead of computation and communication are impractical to use in WSNs; security in sensor networks is, therefore, a challenge. Access control is a critical security service that offers the appropriate access privileges to legitimate users and prevents illegitimate users from unauthorized access. However, access control has not received much attention in the context of WSNs. This paper provides an overview of security threats and attacks, outlines the security requirements and presents a state-of-the-art survey on access control models, including a comparison and evaluation based on their characteristics in WSNs. Potential challenging issues for access control schemes in WSNs are also discussed

“…Despite the advantages of such study, they did not consider other types of security threats. H. A. Maw et al [33] proposed an Adaptive Access Control model that provides fine-grained access control for medical data in BSNs and WSNs. The model considers privilege overriding and behavior, so users might be able to override a denial of access when unexpected events occur.…”

Abstract-Recent years have witnessed a widespread availability of electronic healthcare data record (EHR) systems. Vast amounts of health data were generated in the process of treatment in medical centers such hospitals, clinics, or other institutions. To improve the quality of healthcare service, EHRs could be potentially shared by a variety of users. This results in significant privacy issues that should be addressed to make the use of EHR practical. In fact, despite the recent research in designing standards and regulations directives concerning security and privacy in EHR systems, it is still, however, not completely settled out the privacy challenges. In this paper, a systematic literature review was conducted concerning the privacy issues in electronic healthcare systems. More than 50 original articles were selected to study the existing security approaches and figure out the used security models. Also, a novel Context-aware Access Control Security Model (CARE) is proposed to capture the scenario of data interoperability and support the security fundamentals of healthcare systems along with the capability of providing fine-grained access control.
