Low power VLSI design for a RFID passive tag baseband system enhanced with an AES cryptography engine

Authors

PROCEEDINGS OF THE 1ST RFID EURASIA CONFERENCE , 2007, p. 58-63

Summary

This paper describes a low power implementation of a secure EPC UHF Passive RFID Tag baseband system. To ensure the secure information transaction of the tag, traditionally the focus is on directly applying a low-complexity encryption engine. However, this approach could lead to the problem of known-plaintext attack (KPA). The...

In this thesis Passive UHF RFID Tag Performance characterization and prediction is investigated. To perform tag characterization, we carry out various path loss measurements. Our path loss measurements with varying distance reveals that received power at the reader is not proportional to d to the 4th power as expected from the radar equation. It is deduced that the radar cross section of the RFID Tag is not constant and varies nonlinearly with incident power. Therefore, a power transfer function is investigated to characterize tag backscatter power as a function of incident power. The...
