Description: RFID系统的IEEE的文章，安全协议，认证-
In this paper, we first propose a cryptographic
authentication protocol which meets the privacy
protection for tag bearers, and then a digital Codec for
RFID tag is designed based on the protocol. The
protocol which uses cryptographic hash algorithm is
based on a three-way challenge response
authentication scheme.
In addition, we will show how the three different
types of protocol frame formats are formed by
extending the ISO/IEC 18000-3 standard[3] for
implementing the proposed authentication protocol in
RFID system environment. The system has been
described in Verilog HDL and also synthesized using
Synopsys Design Compiler with Hynix 0.25 µ m
standard-cell library. From implementation results, we
found that the proposed scheme is well suite to
implement robust RFID system against active attacks
such as the man-in-the-middle attack.
