The application of implantable medical devices (IMDs), which solves the problems of geographical distance limitation and real-time health monitoring that plague patients and doctors, has caused great repercussions in the medical community. Despite the great potential of wide application, it also brings some security and privacy issues, such as the leakage of health data and unauthorized access to IMDs. Although a number of authentication and key agreement (AKA) schemes have been developed, we find that some subtle attacks still remain to be addressed. Then we propose an improved AKA scheme which achieves strong security features including user anonymity and known key security. It is formally proved to be secure under the Real-or-Random model. Moreover, a comprehensive security analysis shows that our scheme can resist various attacks and satisfy the desired requirements. Finally, the performance analysis shows the superiority of our protocol which is suitable for the implantable medical system.

Abstract Internet of Things (IoT) is a developing technology in our time that is prone to security problems as it uses wireless and shared networks. A challenging scenario in IoT environments is Device-to-Device (D2D) communication that an authentication server as a trusted third-party, does not involve in the authentication and key agreement process. It is only involved in the process of allocating long-term secret keys and their update. A lot of authentication protocols have been suggested for such situations. This article demonstrated that three state-of-the-art related protocols failed to remain anonymous, insecure against key compromise impersonation (KCI) attack, and clogging attack. To counter the pitfalls of them, a new D2D mutual authentication and key agreement protocol is designed here. The proposed protocol is anonymous, untraceable, and highly secure. Moreover, there is no need for a secure channel to generate a pair of private and public keys in the registration phase.) Formal security proof and security analysis using BAN logic, Real-Or-Random (ROR) model, and Scyther tool showed that our proposed protocol satisfied security requirements. Furthermore, communication cost, computation cost, and energy consumption comparisons denoted our schema has better performance, compared to other protocols.
