“…The execution process of the decentralized blockchain access control model is shown in Figure 6. The access control models of RABC (Wu et al, 2014), ABAC and UCON (Park & Sandhu, 2002) under the traditional IoMT system all manage access control through centralized authority decisionmaking. Since the computing and storage capabilities of most IoT device nodes are insufficient to support access control management, the execution process of access control is mainly through thirdparty platforms or server devices other than IoT devices.…”

The Internet of Things provides convenience to health systems, especially for remote monitoring of patient physical indicators. While providing convenience, there may be more security vulnerabilities in protecting patient and doctor information and storing health data effectively. As an important research branch in the field of the Internet of Things, the Internet of Medical Things is important for the overall improvement of public health in terms of how to safely conduct technology development and application research and to effectively implement healthcare needs. Blockchain technology is decentralized and untrusted as well as prevents tampering with data and reduces the cost of trust. Its good performance has a strong developmental nature in the healthcare field. This paper analyses how to solve security problems through access control under the Internet of Medical Things, and optimizes three access control methods. The Internet of Medical Things accesses control approach that introduces blockchain technology enhances computational and storage capabilities and is a good solution to the problem of third-party trustworthiness. Even in the face of the rapid growth of end devices, blockchain technology can solve some of the problems arising from access control of massive devices through three directions: hierarchical management, compressed storage and performance optimization. Finally, it provides directions for future research on the security aspects of blockchain technology under the Internet of Medical Things.

“…For multi-domain SIoT-based systems, the smart devices belong to different authority domains. In order to determine the device role in a foreign domain and get access to the required resource, the role mapping concept is leveraged between the hierarchical access control structures to map the access requester security level in its target domain [22]. However, the social conditions such as the type of the social relationship between the access requester device and the resource device are not considered in the role mapping.…”

The Social Internet of Things (SIoT) paradigm has been integrated in the education domain to enable educational IoT devices to establish social relationships and exchange academic services. Nonetheless, the social relationships are not adapted to the educational context where devices must be socially linked based on their academic roles and activities. Furthermore, the exchange of services raises the requirement to implement an access control mechanism. In SIoT, social constraints such as the social relationship type and contact frequency are critical requirements to make an access decision. However, these constraints cannot be specified using the eXtensible Access Control Markup Language (XACML) standard as device attributes nor as contextual conditions. In this paper, we propose an Educational Social Internet of Things (EducationalSIoT) platform implemented as an application-specific blockchain where we define new social relationships for educational devices. To control the access to the academic services, we suggest extending the XACML policy model by considering the social requirements, and accordingly, we adjust the policy evaluation process and suggest priority-based combining algorithms. Additionally, our platform ensures the delegation of access permission by defining delegation policies and controlling the delegation operation with consideration of the social features. The simulation results show that by integrating social features, an access request is evaluated in 0.22ms and a delegation request is evaluated in 0.32ms. Finally, we guarantee that our platform is protected against the man-in-the-middle and replay attacks.

“…Standard access control models are widely used in inter-domain authorization, but they face a challenge of adopting them to the inter-domain constraints. Since cross-domain authorization requires to determine the role of the user requesting the remote access, the role mapping concept is proposed via creating a single-goal-role [29], mapping between hierarchical access control structures [19,30], or using the ontology [31,32]. The single-goal-role consists of finding the appropriate role for a local user allowing him to access the remote resources.…”

The Social Internet of Things (SIoT) is a new paradigm which represents a promising business solution proposed to exploit the large volume of data generated by the IoT devices. Accessing the shared resources and services in SIoT faces one major security challenge among others: access control. An access control mechanism evaluates the access policies and performs consecutive re-delegation operations based on delegation policies. However, the re-delegation cannot be performed when no trust relationships exist between the access requester devices and the permission delegator devices. To overcome this issue, we propose to perform friendship-based re-delegations through a path of trust social relationships. To find this path, we suggest to fetch the social device's profiles by integrating a caching strategy. The evaluation results show that a friendship-based delegation can be applied for any system distinguished by a distributed architecture, large scalability and high dynamicity such as the SIoT.
