应用背景摘要标签碰撞仲裁无源RFID标签是重要的快速识别。本文提出了一种自适应记忆的标签防碰撞协议这是一个进步在查询树协议。识别标签的效率，我们使用关于标签的读者已经知道。我们如何评估许多冲突可以通过该协议在查询树协议。关键技术无线射频识别（RFID）系统是一种自动识别系统。RFID阅读器识别对象通过与标签具有无线通信唯一的ID信息，并附加到对象。的读者必须能够识别标签尽快。然而，读者或标签的信号碰撞，因为他们沟通在共享无线信道干扰和碰撞快速识别。读者可能不认识所有的由于碰撞的物体。因此，防碰撞协议这减少碰撞和识别标签无论发生碰撞是必需的。

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.

然后再检查一下tcl，tck的版本号跟路径，如果不同的目录跟你自己的版本号换了版本号一样。
