摘要
作为一种非接触式的自动识别技术,射频识别(RFID)技术在社会生活中起到越来越重要的作用,但是安全隐患的存在制约了RFID的广泛应用。分析了现有的RFID安全机制,在EPCglobal UHF协议规定的基础上,提出了针对标签和阅读器之间安全通讯的模型,并且对原有的DES加密算法进行改进,降低了标签电路的尺寸,同时也提高了RFID读写系统的安全性。
Radio Frequency Identification（RFID）,as a non- contact auto- identifying technology,has become increasingly crucial in our daily life. But there are some potential problems in security and privacy because of the wireless communication between readers and tags. This paper illustrates a new secure communication model based on the existing RFID security system, which meets the EPCglobal Class1 Gen2 protocol. An improved DES encrypt algorithm is also applied in this system to enhance the security.
