具有射频识别功能的嵌入式低功耗智能钥匙设计
Design of Embedded Low-power Intelligent Key with Function of Radio Frequency Identification
摘要
Abstract
For the matching of multiple locks and multiple keys,a low-power intelligent key which is applied to the active authentication with embedded radio frequency identification is designed.The management of multiple locks is realized by means of authorized registration and active two-way authentication,where password dictionary encryption and quasi dynamic password index are used to ensure that the authentication process is reliable.According to the low power requirement of the key,a 1 s periodic sleep with 0.005 s wakeup mechanism is proposed to reduce the power consumption of authentication card as much as possible.Experimental results show that,the power consumption of the intelligent key sleep mode is less than 2 μA,and it meets the requirement of matching and security authentication between multiple keys and multiple locks.关键词
