Secure Management of Healthcare Data in Fog and IoT Networks: A Short Survey on Existing Security Protocols

In recent years, multi-media data regarding various applications have emerged exponentially over the Internet of Things (IoT). Generally, these gathered data are fed to the cloud for storage and further processing. The fog layer is incorporated here which acts like a bridge and performs communication between the cloud and IoT devices. This fog-derived IoT network offers services by effectively analyzing and computing information gathered by IoT devices with the help of sensors. Though, it has two major challenges energy and security. Further, fog computing aims to minimize the overhead of cloud computing to provide network services to satisfy secure data transmission. Nowadays, various security protocols have been suggested to overcome the security challenges in the existing fog-driven IoT models. Moreover, among various applications, the healthcare application requires an efficient data management strategy with maximum security, and thus, this paper aims to study the various research works on healthcare data management in Fog and IoT networks with different authentication protocols. The existing research works on Foga-ssisted healthcare data management systems in IoT are categorized for guiding the upcoming researchers in this field. Moreover, this review discusses different authentication protocols, performance metrics analyzed for validation and diverse tools used for implementation. To conclude, the research challenges and gaps in the field of healthcare data management in fog and IoT networks are studied. This analysis further substantiates the requirement for a coherent technique for healthcare applications in fog computing.
