Survey of Authentication Schemes for Health Monitoring: A Subset of Cyber Physical System

Cyber Physical System (CPS) is an emerging field and further considerable research topic in multiple domains. Health monitoring is one of sub-fields in Cyber Physical System and relies heavily on wireless environment for connectivity. Due to prevailing interest in this field, security of the data is key concern when it is accessed from remote location. As it is being utilized by medical practitioner to make health related decisions risk of intrusion is always present. Any breach can cause adverse effects to patient's health. Therefore, importance of data authenticity, freshness and encumbrance free access becomes vital in this perspective. The multiple security solutions have been found in literature. However, security solutions depend severely on authentication schemes. An adequate authentication scheme can ensure protection against cyber adversaries. The main objective of this paper is to present state-of-the-art review on security challenges, security requirements and current authentication schemes available in literature pertaining to health monitoring. These authentication schemes are analyzed on predefined parameter/features in order to testify efficacy of schemes.
