YPAP: The Yoking-Proofs Based Authentication Protocol for Wearable Devices in Wireless Communications

Along with the development of wireless communications, wearable devices are becoming popular for monitoring user data to provide intelligent service support. It makes that the wearable devices confront severe security issues compared with the traditional short-range communications. Due to limitations of computation capabilities and communication resources, it brings more challenges to design security schemes for the wearable devices. In this work, a yoking-proofs based authentication protocol (YPAP) is proposed for the wearable devices during secure wireless communications. In the YPAP, lightweight cryptographic operators are applied to realize authentication between a smart phone and two wearable devices, and yoking-proofs are established for the remote cloud server to perform simultaneous identification during a session. Meanwhile, Rubin logic based security formal analysis is performed to prove that the YPAP has theoretical design correctness. It indicates that the proposed protocol is flexible for ubiquitous wearable device applications.
