Authentication Security in Radio Frequency Identification with IDEA Algorithm

Data security on Radio Frequency Identification (RFID) cards for parking security applications need to be applied for more protection especially information on RFID cards, as well as to improve security on RFID access authentication and verification using cryptography algorithm, one of the algorithms that can be used for authentication and verification in RFID communication process is International Data Encryption Algorithm (IDEA) algorithm, the results obtained that the data security on RFID can work well.
