基于RFID的汽车号牌自动识别系统的安全性设计

Design of security in the vehicle license plate automatic identification system based on RFID

在设计实现汽车号牌自动识别系统时提出了隐秘起始地址、随机数初始化两种新方法,而且还采用了MD5加密算法、标签锁定等常规方法,并把这些方法有效地结合起来,从而保证系统中号牌数据的安全可靠.多次的实验结果和长时间的系统运行情况都证明了这些方法足够保证RFID标签中的号牌数据安全可靠.

In order to ensure data security in the vehicle license plate automatic identification system, this paper propose two new methods： secrete starting address and initialize with random number, moreover adopt some general methods such as MD5 encrypt algorithm, locking tag, effectually band together these methods in the system. And prove that these methods can ensure enough data security through repetitious experiment results and long-running stably status of system.
