Secure communication between wireless medical sensor networks and data servers using paillier and elgamal key cryptosystem

A wireless sensor network is used to sense the infected person's body condition and transmits the collected data to the database. The details including temperature, heartbeat, and blood pressure are sensed using appropriate sensors and stored in the servers. The details are encrypted using Paillier and ElGamal key cryptosystems for providing high security. The server is helpful in providing querying service to users. The encrypted data is fetched from the server and decrypted before authentication. To prevent the patient data from the attackers, new protocol is proposed, where the patient details are converted into numerical form. This numerical form is difficult to understand by the attackers. Then the numerical values are sent to servers through secure channels. The patient data are securely distributed by employing the Paillier and ElGamal cryptosystems. This project focuses on secure storage and communication. The secure data will be implemented based on cryptographic principle.
