摘要
为保障食品安全、提高数据传输的安全性,设计了一种NB-IoT+云检测环境下的肉制品原产地可信溯源系统;使用改进后的RSA加密算法对溯源系统各类型肉制品信息进行加密,降低了检测过程中计算量和硬件加密时间。各项检测结果表明:所构建的肉制品原产地可信溯源系统各部分运转正常且溯源成功率高于99.8%,在检测终端网络信号强度大于-100 dBm时,检测通信成功率超过99.8%,GPS平均定位误差4.95 m,能够满足实际需求。
In order to ensure food safety and improve the security of data transmission,a trusted traceability system of meat products'origin in NB-IOT+ cloud detection environment is designed;the improved RSA encryption algorithm is used to encrypt all types of meat products'information in the traceability system,which reduces the amount of calculation and hardware encryption time in the detection process.The results show that the system works well and the success rate of traceability is higher than 99.8%When the network signal strength of the detection terminal is greater than-100 dbm,the success rate of detection communication exceeds 99.8%,GPS average positioning error 4.95 m To meet the actual needs.
