摘要:

提出了一种利用人体内部的生物特征来进行认证的生物识别电子锁设计方法,简称为 PBLock。该方法通过人手指与无源式射频标签的接触,利用后向散射的射频信号传递人体指尖阻抗特征来实行认证。这样的认证方式的优势在于,由于人体阻抗不易采集,加之与设备(RFID 标签)的硬件特征充分融合,大大增加了攻击者复制和克隆的难度。为保证系统的可用性和高效性,利用标签天线剪切式认证优化机制,有效提升了人体阻抗敏感度。同时,利用RFID系统的电磁能量优势讨论了被动驱动的可行性。实验评估结果表明,PBLock的认证准确率可达 96%,平均单次认证的时间花销是1.4 s。另外,从实际环境出发提出了攻击模型,通过深入分析发现,PBLock 可以有效防止伪造攻击、模仿攻击和重放攻击,为新型生物识别电子锁的应用安全提供重要保证。

Abstract:

A biometric lock design method was proposed based on the internal features of human body, namely PBLock.It used the backscattered RF signals to collect the impedance characteristics of human fingertips through the contact between human fingers and tags.The advantage of such authentication method is that the human impedance was not easy to be stolen, and it was fully integrated with the hardware characteristics of the device (RFID tags), which greatly increased the difficulty for the attacker to copy and clone.To ensure the availability and efficiency of the system, an optimization authentication mechanism was proposed by cutting tag antenna, which effectively improved the impedance sensitivity.Moreover, the feasibility of passive drive was discussed by using the electromagnetic energy advantage of RFID system.Through a large number of experimental evaluations, the authentication accuracy of PBLock can reach 96%, and the average time cost of a single authentication is 1.4 seconds.Some attack models were presented based on practical environment.The results show that PBLock can effectively prevent counterfeiting attack, impersonation attack and replay attack, which provides an opportunity for the secure application of new biometric electronic locks.
