【摘要】 在比较国内外农产品追溯系统建设模式的基础上,系统地提出了一种基于行政监管的适合中国国情的水产品追溯系统架构方式,设计了一种基于行政区域代码的水产品追溯编码方式,突破了基于AES(advanced encryption standard)的水产品追溯监管码十进制分组压缩加密算法,建立了基于USB Key的水产品监管码密钥动态分配技术,生成了融合一维码、二维码的水产品混合条码标签。经在多省测试应用,水产品追溯监管系统安装部署简便,可护展性强,追溯码输入方便、安全性高。更多还原

【Abstract】 After comparative analysis on the construction mode of domestic and foreign agricultural product traceability system,an aquatic product traceability system architecture was developed based on the administrative supervision and Chinese situation.The key technologies of the aquatic products traceability were studied,including the aquatic products traceability code scheme based on administrative divisions codes,the decimal group compressed encryption algorithm of aquatic products code based on AES(Advanced Encryption Standard),the dynamic allocation technology of aquatic traceability code based on USB key.The mixed aquatic products label including one-dimensional code and two-dimensional code were designed.The results of application test in several provinces showed that the system could be easily installed and deployed,and the traceability code had the characteristics of easy input and high safety.更多还原
