Securing RFIDs by Randomizing the Modulation and Channel
summary
RF‑Cloak claims to protect deployed commercial RFID cards without modifying them by randomizing modulation and the channel; it provides theoretical proofs and an empirical demo on USRP prototype hardware that uses a rotating antenna with rapid switching (1700 rpm) to emulate many antennas. Tests on commercial cards including transit fare media show eavesdroppers hit BER ≈ 0.5 (0.498 for single‑antenna; ≈0.5 across 2–5 antenna MIMO adversaries) so attackers cannot recover bits.
