Implementation of Cloud-Assisted Secure Data Transmission in WBAN for Healthcare Monitoring

This work presents the cloud-assisted secure WBAN for healthcare application. There are various security issues associated with WBAN, which need to be solved to provide a secure real-time health monitoring system. Through this implementation, the patient’s vital signals can be accessed in a secure manner in real time remotely by sensors and networks without visiting doctor’s clinic or hospital. Here, we provide the cost-effective solution for the transmission of the patient’s health data to doctor with proper confidentiality, authenticity, freshness, and security using cloud computing. In this work, the biosignals of patients and doctors are used to provide authenticity and vital signals are encrypted by using Advanced Encryption Standard (AES) for the secure m-health application. We have experimentally analyzed the average end-to-end delay for secure healthcare application is 14.59 and 19.31 ms in off-peak hours and peak hours respectively. This delay is only 5.84% in off-peak hours and 7.72% in peak hours of permissible delay of 250 ms for medical application.
