Abstract. With continuous improvements in the efficiency of micro-
electronics, it is now possible to power a general-purpose microcontroller
wirelessly at a reasonable range. Our implementation of RC5-32/12/16
on the WISP UHF RFID tag shows that conventional cryptography is
no longer beyond the reach of a general-purpose UHF tag. In this paper,
(1) we provide preliminary experimental data on how much computa-
tion is available on a TI MSP430F1232 microcontroller-based RFID tag
containing approximately 8 KBytes of flash and 256 bytes of RAM, and
