“…In [52], Hossein et al proposed the BCHealth architecture that allows data owners to specify their security policies over their data. For that purpose, the authors used two chains, where the first chain was used to store data transactions and the second one concerned access control policies' storage.…”

“…Cr1: number and type of the blockchain After a deep analysis of the blockchains used in the proposed access control solutions (summarized in Table 3, it can be stated that no solution used a public blockchain. Some authors deployed a private one in [27,34,36,41,44,49,52]. In parallel, others used a consortium blockchain in [37,42,57,58,61,68].…”

“…Regarding the number of the blockchains, the authors in [37] employed a hierarchical blockchain architecture to ensure good scalability, high throughput, and less transaction latency. In [52], Hussein et al used two blockchains, namely policy chain and data chain. Conclusively, it is safe to estimate that the choice of the type of blockchain is related to the nature of the stored data.…”

The Internet of Things is gaining more importance in the present era of Internet technology. It is considered as one of the most important technologies of everyday life. Moreover, IoT systems are ceaselessly growing with more and more devices. They are scalable, dynamic, and distributed, hence the origin of the crucial security requirements in IoT. One of the most challenging issues that the IoT community must handle recently is how to ensure an access control approach that manages the security requirements of such a system. Traditional access control technologies are not suitable for a large-scale and distributed network structure. Most of them are based on a centralized approach, where the use of a trusted third party (TTP) is obligatory. Furthermore, the emergence of blockchain technology has allowed researchers to come up with a solution for these security issues. This technology is highly used to record access control data. Additionally, it has great potential for managing access control requests. This paper proposed a blockchain-based access control taxonomy according to the access control nature: partially decentralized and fully decentralized. Furthermore, it presents an overview of blockchain-based access control solutions proposed in different IoT applications. Finally, the article analyzes the proposed works according to certain criteria that the authors deem important.

“…However, the use of Cloud couputing for storage retrieve of data from the Cloud increases latency, in our work we are using FC in our architecture to reduce the latency needed in real-time applications such as telemedicine. A Blockchain-based architecture for e-health applications is proposed in [27], where they modify the classic BC structure in order to overcome its challenges in IoT applications. To this end, they cluster the miners of BC, store and process data at the nearest cluster to the patient.…”

In the fight against the COVID-19 epidemic that is currently a major global public health issue, social distancing has been imposed to prevent the massive transmission, thus doctors in hospitals have turned to telemedicine in order to be able to monitor their patient notably those suffering from chronic diseases. To do so, patients need to share their physiological data with doctors. In order to share this data safely, prevent malicious users from tampering with it and protect the privacy of patients, access control becomes a fundamental requirement. In order to set up a real-time (Internet of Thing) IoT enabled healthcare system (HS) scenario like telemedicine, Fog computing (FC) seems to be the best solution comparing to Cloud computing since it provides low latency, highly mobile and geo-distributed services and temporary storage. In this paper, the focus is on access control in the telemedicine systems. Our proposal is based, on one hand, the concept of Fog computing to ensure the distributed aspect needed in the monitoring of patient health remotely; and on the other hand Blockchain (BC) smart contracts, in order to provide a dynamic, optimized and self-adjusted access control.
