IMPLEMENTATION OF AES AND ELGAMAL ALGORITHMS FOR A SECURE RFID DATABASE IN HEALTHCARE

The work proposed a hybrid encryption algorithm for security of database and protection in radio frequency identification system using an advanced encryption standard and elgamal encryption as a cryptographic primitive. The algorithm protects high-valued sensitive health records against malicious users. With the developed system, one can provide a proof for each record stored in the database of the RFID system because it is sufficiently robust to withstand replay attack, eavesdropping attack and backward traceability. All records are randomized and each tag has its own unique identification data. In the proposed solution, the database was secured using hybrid encryption standard. The system is user friendly and interactive. Security enhancement will be achieved with the new system. The software when deployed will assist health institutions to keep track of their patients’ record easily. The New Hybrid Encryption algorithm takes much longer time compare to time taken by AES and Elgamal. Since the hybrid algorithm takes longer time for both encryption and decryption, it makes it more secure, since the higher the encryption processes the longer it will take for a hacker to break the encryption algorithm, since computing power is on the increase, speed will not be a problem in the nearest future and as such, in certain classified database, one cannot trade security with speed. This study will be useful in the protection of data stored in organizational databases. Data/information transmitted via insecure media will be received without interference or loss of data or information of any kind. It also reduces theft to its barest minimum. The hybrid security system will help individuals and organizations to protect their information from unauthorized user. Securing sensitive data from illegal access, theft and forging becomes a lesser challenge for different organizations, like security agencies, higher institutions and private sectors. This will make information stored or shared confidential. This study significant importance to Nigeria Police Force because it will forestall tampering of records but rather ensure its integrity
