Abstract:


This paper presents a novel authentication and encryption method for an RFID system. In this paper, DES (Data Encryption Standard), algorithm will be used to encrypt and verify accuracy data within an RFID tag. The new DES algorithm use permutation box with assigned a permutation pattern keeps changing in time. The proposed technique increase the difficulties for any hackers behave. The proposed algorithm measured and evaluated the time to read/write encrypted data and compared that with the time to read/write unencrypted data. Also, this study measured and analyzed the effect of encryption, on the accuracy of the read/write function in an RFID infrastructure. Experimental results show that proposed method has more efficient performance with the encryption data group, since the encryption time is less than 1 ms, it is negligible compared to the transmission time.
