One embodiment of a cryptographic lock includes: (1) a shape memory alloy (SMA) having a first and second phase, wherein the first phase inhibits access to an asset and the second phase allows access to the asset and (2) an RFID transponder, coupled to the SMA, configured to receive an authentication signal from an RFID transceiver and, based thereon, energize the SMA to temporarily change the SMA from the first phase to the second phase.
