RFID打印机程序 可以实现条码的打印和写入数据

说明：  为了系统的安全性，为门禁控制系统增加了登录功能，通过从后端数据库录入管理员信息，包括用户名与密码，便可在用户界面使用数据库中的信息进行登录，极大的保证了系统的安全性。用户可以通过数据库匹配方法来对ID卡进行登记、删除等操作。(In order to ensure the security of the system, the login function is added to the access control system. By inputting administrator information from the back-end database, including user name and password, the information in the database can be logged on in the user interface, which greatly guarantees the security of the system. Users can register and delete ID cards through database matching method.)

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.
