The Mifare Classic card is the most widely used contactless smart card in the world. Since the Mifare Classic card was cracked, how to protect data in Mifare Classic card becomes a big challenge. In this paper, a novel data protection scheme for this RFID card is presented. By combining Arnold transform for data hiding and SHA-1 and Arnold transform based auth code for tamper and counterfeit detection, it can guarantee data integrity and confidentiality in Mifare Classic card.
