Protection and Security for Wireless Medical Sensor Data

Computer Engineering

In recent years, wireless sensor networks are widely used in healthcare applications, such as hospital monitoring. Wireless medical sensor networks are more effective to eavesdropping, modification, replaying attacks and impersonation than the wired networks. A lot of efforts have been done to secure wireless medical sensor networks. The existing systems can protect the patient data during transmission, but cannot drop the inside attack where the administrator of the patient database requires the sensitive patient data. In this paper, we propose a practical approach for preventing the inside attack by using multiple data servers to store patient data. The main contribution of this paper is securely distributing the patient data in multiple data servers and employing the Paillier and ElGamal cryptosystems to perform statistical analysis on the patient data without compromising the patients’ privacy.
