摘要
RFID射频识别技术的应用给人们提供了一种严格高效的管理方式,大大提高了工作效率及服务质量,但同时也存在一些相关的安全问题,制约了RFID技术的应用及推广;针对Mifare射频IC卡识别系统中的应用扇区密钥长度有限、密钥规定单一等缺点,提出了基于TEA加密算法的动态密钥设计方案,引入随机数,利用TEA算法加密明文数据包,并在8位单片机PIC16F873A上进行应用实现;试验和实践证明该方案高效安全可行,大大提升了Mifare射频IC卡识别系统的安全性能,有广泛的应用价值。
The application of RFID technology provides a strict and efficient method, which will improve the performance of the management, however with the unchanged limited length key in a sector, the application of Radio Identify System of Mifare IC Card is seriously restricted. A Dynamic-Key design scheme based on TEA encrypt algorithm is provided in this paper, which imports the random mumber, and the solution can be realized in a 8-bit single-chipcomputer PIC16F873A.This scheme is proved to be feasible and efficient by experiment and in practice, which will bring a great application value for the Mifare IC Card.
