Abstract

Of late, E-health monitoring is gaining its limelight because of its flexibility of service. This methodology makes it possible to monitor a patient in a remote area, by exploiting wireless biosensors attached in the patient’s body. These biosensors collect different physiological signals from the human body and forward all the collected information to the server or to the doctors. This data transmission is vulnerable to several security attacks. It is necessary to provide security and hence a three layered lightweight symmetric key based cryptographic system is proposed. This system ensures several security measures such as access control, data confidentiality and integrity etc. Finally, the proposed system is analyzed with several performance metrics. The system proves its efficiency and is shown in graphical results.

Keywords:

Biosensors, E-health monitoring, symmetric key based cryptography, wireless body sensor networks,
