- Abstract
- In this paper, we implemented the low power and small area hardware of SHA-1 hash function for RFID tag. For small area design we optimized operation logics and for low power design we minimized data transitions of register memory. It is implemented with 10,641 gates at Samsung 0.25μm CMOS technology and it needs 330 operation clocks for one hash function of 160-bit data. Its power consumption is 19.5uW at 100kHz operation clock1. © 2006 IEEE.
