Provable and secure Two-Party Authenticated Key Agreement (2PAKA) Protocol for Internet of Health Things

In the perception layer of the Internet of Health Things, deploying new nodes necessitates the usage of a Two-Party Authenticated Key Agreement (2PAKA). A malicious node deployment in the perception layer of Internet of Health Things can disrupt the functioning of the complete application based on Internet of Health Things. To be used in real-world and practical applications, a new node authentication and key exchange mechanism must meet specific security and functional requirements. Although protocols and schemes for new node deployment have been proposed in the literature but for the practical applicability of the scheme it must conform to certain functional and security specifications, In this paper, an ECC-based new node authentication and key exchange method for the perception layer of the Internet of Health Things is presented. The proposed scheme has been analysed using Random Oracle Model. In addition to meeting basic security and functional specifications, the method has been validated on AVISPA tool which indicate that the proposed scheme is safe against various attacks.
