Integration of Lightweight & Energy Efficient Cipher in Wireless Body Area Network Fore-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. This led to a high demand for a continuous care that can be achieved by adopting an emerging technology of e- Health monitoring system using Wireless Body Area Network (WBAN) that can collect patient’s data. Since patient’s data is private, securing the communication within WBAN becomes highly essential. In this research thesis, we propose an architecture to secure the data transmission within the Wireless Body Area Network (WBAN) in e-Health monitoring. More specifically, our proposed architecture encrypts the patient’s sensed data, collected by sensors and sent to a mobile device, using energy efficient and lightweight encryption algorithm (LEA). Our implementation results show that choosing LEA encryption algorithm is the best option for encrypting data that is transmitted from a body-wearable sensor to a mobile device. This approach ensures the security and the privacy of patient’s “critical” data transmitted on WBAN, and is used in e-health monitoring. Our contribution in this research are twofold. First, conducting an extensive study to determine the best cipher that is suitable for WBAN. Second, determining and implementing LEA as the best solution for WBAN in terms of lightweight and energy efficiency, which are critical factors in Body Sensor Network
