加密技术在出租车计价传感器上的应用

The Application of the Encryption on Sensor of Taximeters

该文把加密技术用于出租车计价传感器中,在分析现有出租车传感器漏洞的基础上,提出了出租车加密传感器的加密模型和系统结构模型,采用PIC12C508A、PIC12CE518A和INTER8031单片机完成了密码传感器系统中加密器、解密器和密码写入器软硬件系统设计,加密后的密码传感器大大提高了出租车计价器计费的准确性和安全性,解决了现有出租车计价器可靠性不高和难以实现统一管理的难题。

This paper applies the encryption to the sensor of taximeters.It provides encrypt ion models and system structure model of encrypting sensor of taximeters based on analyzing bugs of sensor of taximeters now,then designs hardware of Encrypting machine,decoding machine and machine that writes into secret code using PIC12C508A,PIC12CE518A and INTER8031.Secret code sensors after encrypting raise accuracy and security of taxi charges greatly,and solve existing difficult problems of reliability and management in unison.
