Providing Security to Medical Data

Wireless Medical Sensor Network (WMSN) is used in healthcare applications which have the collection of sensors connected to body or emergency care unit to monitor the patients’ vital signs. The privacy details of the patients have to be secured. Lot of techniques have been proposed to secure the health data. But there are some loop holes still exist for the attackers to hack the data. This is the major problem and to solve this issue some techniques have to be invented. In the proposed system we are comparing the four existing cryptosystems for its computation time. We choose the best one among them to encrypt the data.
