Lightweight encryption algorithm in wireless body area network for e-health monitoring

There is an increase in the diseases of the circulatory system in United Arab Emirates, which makes it the first leading cause of death. Therefore, there is a high demand for a continuous care that can be achieved by adopting an emerging technology of e-Health monitoring systems using Wireless Body Area Network (WBAN) that can collect patient's data. Since patient's data is private that makes securing the WBAN is essential. In this paper there is a proposed design architecture to secure data transmission from WBAN sensor to mobile in e-Health monitoring system by encrypting the vital signs of a patient using Lightweight Encryption Algorithm (LEA).
