ID-Based Proxy Signature with Key-Insulated Scheme for Portable Healthcare Devices in 5G-IoHT

Abstract

5G networks provides quality of experience and amount of devices communication. Internet of things (IoT) becomes a concept of enclosing several technologies and a network between objects and human beings, and Internet of Health Things (IoHT) combines healthcare systems with portable healthcare devices with 5G environment providing solutions of network layer to solve challenges of smart medical healthcare solutions. IoHT plays a major role in enlightening the people health level and increases the worth of life. However, security and privacy issues of IoHT are rising, and key exposure is one of the problems for devices in IoHT which may endanger not only IoHT but safety and interest of patients and medical institute. In this paper, we introduce and evaluate ID-based proxy signature with key-insulated scheme for portable healthcare devices in 5G-IoHT. Proposed scheme allows emergency secure communications between patient and medical staff and can solve problems above in an efficient way. We also provide security evaluation to prove that proposed scheme is secure enough to against potential attacks.
