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.
