Abstract
To improve the security performance of passive Internet of Things,encryption algorithms are often added to sensor de-vices.The traditional encryption algorithm of passive sensor terminals often uses pseudorandom numbers to encrypt data,which has great security risks,and the existing methods of generating true random numbers require a special true random number genera-tion circuit,which is expensive and not suitable for passive sensor terminals.At the same time,the encryption algorithm in the existing passive sensor terminal cannot be reconfigured,and the conversion mode is few,so it is difficult to further improve the se-curity.Therefore,this paper designs a wireless passive reconfigurable remote security sensing terminal.It adopts the MCU to im-plement the standard RFID communication protocol instead of the dedicated RFID chip and can modify the MCU code arbitrarily according to various application scenarios,thereby achieving the reconfigurable function of the sensing terminal.And it uses a compatible true random number generator based on RF signal and ADC residuals to generate true random numbers without special circuit.The enhanced reconfigurable encryption algorithm combined with true random numbers greatly improves the encryption performance of sensing terminal.At the same time,the multi-source energy collection circuit architecture improves the receiving sensitivity of the terminal,so as to realize the long-distance communication function of the sensor terminal.关键词
