The limited computational capabilities of low-cost RFID cards may induce security weaknesses stemming from concessions made in hardware. In particular, RFID cards with weak pseudo-random number generators (PRNGs) can leak secret information. Current generation RFID cards, such as the Mifare DESFire EV1, improve on the cryptographic and random number generation capabilities of previous cards such as the Mifare Classic. However, there is not yet a published analysis on the quality of the true random number generator (TRNG) used in Mifare DESFire EV1 cards. This paper represents the first study of the randomness of the DESFire EV1, and shows preliminary results that highlight a distinct pattern of biases in its TRNG.
