PUF for device authentication in multi-hop body area networks

Abstract

Wireless sensor technology has several applications in the military, the medical field, and the corporate world. A Wireless Body Area Network (WBAN) is a novel use of wireless sensor networks in the area of human health monitoring; it enables individuals to keep track of their personal vitals in real time and respond appropriately in the event of an emergency. Access to reliable data, as provided by nodes in WBAN, is crucial for providing successful patient care. We solved the problem of unreliable data in this study by assigning trustworthiness ratings to each sensor node. In this research, we employ a physically burning anthracite or bituminous coal function (PUF) as a hardware-centric security factor for cloud-based lightweight identification in multi-hop oriented WBAN. In this setup, the cloud is the TTP that records all sensors. The sensor node and the CR pair are uploaded to the cloud, where the washbasin validates them. The authentication time for nodes was cut down by using a hierarchical system. Hence, the cloud server has a hierarchical system for storing credentials for nodes. There was a considerable improvement over the baseline system in terms of the ratio of packets delivered, packet arrival quality, packet delivery latency, and the quality of the intermediate hops in our proposed system.
