RFID Overview● Tag types: Various sizes and shapes e.g. Keyring; Credit-Card● Tag types: Active (Battery) and Passive (No internal Power Source)
RFID Security● HID Proxcard2 found mostly on Access control system. Come with no authentication, encryption, or any other real security mechanism. Just plain-text.● The most popular RFID Card types (Mifare Ultralight; Mifare Classic; DESFire). Use ISO 14443A & operating on 13.56mhz. In the year 2007, Researchers found weakness of Mifare classic protocol. And managed to crack the Crypto1.● NFC Credit cards support EMV-style contact-less payment. EMV stands for EuroPay, Master-card, Visa, which is a global standard for bank smart cards.● The core of the EMV protocol is based on the transmission of Application Protocol Data Units (APDUs). Most of the APDUs sent between the two devices, are transmitted in plain-text. Cryptographic security is only employed in the authorization phases of a transaction.
