“…Implementations must have a small footprint not to exceed the costs, and they have to be designed for low power in order to allow a certain reading range. A lot of proposals have been published so far that deal with lightweight cryptography for RFID by using coupon-based signature functions like GPS [23,18], stream ciphers [7,12,9], asymmetric algorithms like ECC [30,4], or symmetric algorithms like AES [10], PRESENT [6], SEA [28], HIGHT [13], or DES variants [22]. At the time, the security features of conventional RFID tags range from simple secure memory-lock functionalities to integrated cryptographic engines like Mifare [19], SecureRF [26], or CryptoRF [2].…”
