摘要： 针对低成本电子标签安全隐私保护能力和防跟踪能力较弱的问题，采用读写器代理生成随机数的方法，提出一种面向大容量被动型标签的新型无线射频识别(RFID)安全认证协议。理论分析证明，该协议具有前向安全性，能够防止位置隐私攻击、窃听攻击，保障数据的保密性、可靠性和一致性，且硬件复杂度较低，适用于低成本电子标签。

Abstract: The method of implementation of security and privacy in low cost tags is a key technique to be solve in research field. Based on the use of pseudo-random number generation function in writer/reader device instead of in tags, this paper proposes a new Radio Frequency Identification(RFID) mutual authentication protocol, focus on high-capacity but low-cost tags, which possesses forward security ability and can defeat location privacy attack, relay attack, eavesdropping attack and can protect data from being falsifying. The new scheme effectively solves problems of RFID security and privacy with lower complexity of hardware, so it is useful for low-cost RFID tags.

Key words: Radio Frequency Identification(RFID), random number, privacy, security authentication, low-cost tag
