Emerging technologies rapidly change the essential qualities of modern societies in terms of smart environments. To utilize the surrounding environment data, tiny sensing devices and smart gateways are highly involved. It has been used to collect and analyze the real-time data remotely in all Industrial Internet of Things (IIoT). Since the IIoT environment gathers and transmits the data over insecure public networks, a promising solution known as authentication and key agreement (AKA) is preferred to prevent illegal access. In the medical industry, the Internet of Medical Things (IoM) has become an expert application system. It is used to gather and analyze the physiological parameters of patients. To practically examine the medical sensor-nodes, which are imbedded in the patient’s body. It would in turn sense the patient medical information using smart portable devices. Since the patient information is so sensitive to reveal other than a medical professional, the security protection and privacy of medical data are becoming a challenging issue of the IoM. Thus, an anonymity-based user authentication protocol is preferred to resolve the privacy preservation issues in the IoM. In this paper, a Secure and Anonymous Biometric Based User Authentication Scheme (SAB-UAS) is proposed to ensure secure communication in healthcare applications. This paper also proves that an adversary cannot impersonate as a legitimate user to illegally access or revoke the smart handheld card. A formal analysis based on the random-oracle model and resource analysis is provided to show security and resource efficiencies in medical application systems. In addition, the proposed scheme takes a part of the performance analysis to show that it has high-security features to build smart healthcare application systems in the IoM. To this end, experimental analysis has been conducted for the analysis of network parameters using NS3 simulator. The collected results have shown superiority in terms of the packet delivery ratio, end-to-end delay, throughput rates, and routing overhead for the proposed SAB-UAS in comparison to other existing protocols.

Background and Objectives: Technological development expands the computation process of smart devices that adopt the telecare medical information system (TMIS) to fulfill the demands of the healthcare organisation. It provides better medical identification to claim the features namely trustworthy, efficient and resourceful. Moreover, the telecare services automate the remote healthcare monitoring process to ease professional workloads. Importantly, it is conceived to be more timesaving, economical and easy healthcare access. Methods & Analysis: Cloud-Based Medical Healthcare (CBMH) system is a standard platform that gives its support to the patients for emergency treatment from the medical experts over Internet communication. Since the medical records are very sensitive, security protection is much necessitated. In addition, patient anonymity should be well preserved. In 2016, Chiou et al. proposed a mutual authentication protocol for the Telecare Medical Information System (TMIS) using Cloud Environment (CE). They claim that their protocol satisfies patient anonymity. Results: However, this paper proves that the Chiou et al. scheme is not only completely insecure against the patient anonymity, health-report revelation, health-report forgery, report confidentiality and non-repudiation but also fail to validate the service access against verifiability, undeniability and unforgeability. In order to provide better mutual authenticity, this paper suggests the framework of smart service authentication to cross-examine the common secret session key among the communication entities. In order to examine the security properties, formal and informal verification was carried out. Lastly, to prove the security and performance efficiency of a system, the proposed SSA framework was implemented using FPGA and Moteiv TMote Sky-Mote. Conclusion: A proposed smart service authentication (SSA) framework is presented to ensure better data security between the patients and the physicians. The formal and informal security analysis proves the significance of the SSA framework model to withstand the security attacks such as health-report forgery, health-report revelation, server-spoofing etc. As a result, it is claimed that it can be well suited for TMIS.

Internet of Things (IoT) has led to significant advancements in communication technologies, specifically, concerning IoT-based sustainable information systems. Lately, industry-academic communities have made great strides for the development of security in IoT-based applications, such as traffic management, industrial automation systems, military surveillance systems, transportation, parking, etc. The sustainable IoT converges AI and blockchain technologies for enhancing quality of individual’s life. As a result, emerging IoT applications operate a distributed ledger technology to provide robust-level of encryption and execution for contractual agreement that resolves interoperability and security issues. Thus, this article proposes a blockchain-based remote mutual authentication (B-RMA) that considers smart devices and cloud networks to offer security and privacy. The proposed B-RMA can coexist with the IoT-based smart environment to decentralize the processing of user authentication requests. The prominence of the proposed strategies including security efficiency and privacy protection, is evaluated using informal security analysis. Moreover, a runtime platform “Node.js” was used to analyze the communication metrics, such as execution time, throughput, and overhead ratio, over the concurrent requests. The investigation results prove that the B-RMA achieves a scalable environment, accordingly.
