IBA: A secure and efficient device-to-device interaction-based authentication scheme for Internet of Things

The Internet of Things (IoT) enables a variety of services through frequent communication and interaction between devices, bringing a great deal of benefits to human life. The complexity and variability of network environments, together with the diversity of IoT devices introduce a large range of security and efficiency concerns to device authentication. In this paper, a novel interaction-based authentication (IBA) scheme is proposed to respond to the above problems. Device characteristics that can be used as identity credentials are extracted from previous interactions, and secure authentication is realized through elements matching. IoT devices can independently authenticate the identity of other devices without persistent connection to trusted third parties. From the informal analysis and simulation results, IBA supports dynamic adaptability, and high scalability, and resists several well-known attacks, such as reply attacks, impersonation attacks, and man-in -the-middle attacks. The comparison analysis indicates that IBA has better security and performance compared with related authentication schemes, thereby demonstrating it is more suitable for the actual IoT environment.
