An Anonymity, Availability and Security-Ensured Authentication Model of the IoT Control System for Reliable and Anonymous eHealth Services

Abstract

eHealth is supported by electronic processes and communication. The Internet of Things (IoT) is utilized to realize smart healthcare, backup terminal devices are required for reliable eHealth services, and the IoT control system is essential for the security of IoT applications. In 2013, Yang et al. first added backup terminal devices, a status monitor device and an alarm module to the IoT control system and proposed an authentication mechanism for availability and security. In 2016, Chang et al. found that Yang et al.’s authentication model suffers from some drawbacks. In this paper, we adjust the operation and requirements of the IoT control system and take user anonymity into consideration to propose an authentication model for the IoT control system for reliable and anonymous eHealth services. To ensure anonymity of the user and the accessed service, the real identifiers will not be transmitted for untraceability. The proposed authentication model complies with six essential requirements. Via the proposed authentication model, the IoT control system can ensure reliable and anonymous eHealth services with anonymity, availability and security.
