A Novel Multi Factor Authentication and Encryption Scheme to Secure the IOT Healthcare Data in Cloud

Abstract

The Internet of Things (IoT) application is almost ubiquitous across various human disciplines. The IoT can be integrated into electronic healthcare systems to provide more real-time services on demand, which is extremely useful for patients and clinicians. However, the possibility of encountering untrustworthy information and a possible threat to security is immediately raised. In order to secure the IoT healthcare data in the cloud, the proposed system suggests a novel multi-factor authentication and encryption approach using the Optimal key-based Rivest Shamir Adelman (OKRSA) algorithm. First, the user must register with the trusted authority (TA) of the cloud using the Dual Hash-based Secure Hash Algorithm 512 (DHSHA512). After registration, the patient’s data is securely sent to the medical server with the help of the OKRSA algorithm. Finally, the system initiates multi-factor authentication if the user wants to access the files from the cloud medical server. Simulation outcomes proved that the presented scheme offers better security than the previous related schemes.
