| Abstract: | The Internet of Things has opened up new opportunities in healthcare systems. Wireless sensor nodes are used to collect and exchange health-related data in the Internet of Things. In this integration, data is transmitted to medical professionals through unsecured channels to enable them to monitor patients' conditions in real-time. However, due to the high sensitivity of e-health records, there are key challenges such as security considerations, privacy, and authentication in data transmission in heterogeneous Internet of Things networks. This article examines the solution proposed by Masud and colleagues and points out the existing threats and vulnerabilities, such as node clone/replication attacks. To overcome these drawbacks, we propose an improved lightweight authentication protocol for a smart healthcare system. In the proposed protocol, the mutual authentication process consists of two steps. The doctor sends their information for authentication and the desired sensor node ID to the gateway for communication. After successful confirmation of authentication, the gateway node, in turn, sends a message to the sensor node to complete the authentication process. After confirming the authentication process, the node sends a message to the gateway to complete the authentication process and key agreement. Once the authentication process of the sensor node is confirmed, the gateway sends a message to the medical user based on their authentication along with the session key. The security of the proposed protocol is demonstrated through automatic validation of protocols using tools like ProVerif and internet security programs. Additionally, security features and performance analysis are compared to other schemes. The results show that the improved proposed protocol provides a higher level of security while ensuring computational and communication efficiency. It is also resistant to attacks such as mutual authentication, identity anonymity and untraceability, ensures data privacy, and provides perfect forward secrecy, among others.
