摘　　要：针对大规模无线射频识别(RFID)系统,提出一个安全双向认证协议.利用伪随机数生成器计算资源要求低的特性,使协议适用于存储空间小和计算能力不足的低成本标签环境中,采用平面直线斜率计算方法实现认证双方共享一对密钥,将认证的时间复杂度降低到O(1),引入时间戳来抵抗重放攻击,认证结束后进行身份更新防范标签位置追踪.形式化证明显示,该协议实现了标签与读写器的双向认证.仿真结果表明,与现有同类型主流协议相比,该协议认证效率提高了9%.A mutual authentication protocol was proposed for large-scale radio frequency identification（ RFID） system. Taking advantage of pseudo random number generator with little calculation resource requirement,the proposed protocol is suitable for low-cost tag environment with small storage space and low compute power. The slope calculation method of a line was adopted to realize both sides of authentication share a pair of keys and time complexity required to identify a tag can be reduced to O（ 1）. The timestamp was introduced to resist replay attacks,and updates the identity to prevent location tracking. Formal proof shows that it realizes mutual authentication between the reader and the tag. Simulation shows that the proposed protocol can save 9% authentication time compared with some similar existing mainstream protocols.
