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 fr a me 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.
