RF Transceiver Security Against Piracy Attacks

We demonstrate for the first time system-level locking RF transceivers serving as an anti-piracy security technique. The strategy is to make performance key-dependent by leveraging a state-of-the-art logic technique obfuscate digital blocks in signal path. presents several advantages, including general applicability, effective incorrect keys, attack resilience, transparency when correct key used, minimum overheads, and ease of implementation. show that cannot be blindly applied this context and, regard, we how it can adapted towards transceiver locking. A proof-of-concept demonstrated with hardware measurements.
