摘要
为解决当前农产品追溯码安全性不高,难以保证一品一码等问题,以水产品为研究对象,提出了一种水产品追溯码加密算法。在深入分析各种追溯码编码方案和AES加密算法的基础上,对水产品监管码进行编码、压缩和十进制等长加密生成水产品追溯码。实验证明算法可行、可靠;密钥的动态变化和追溯码的唯一性,为追溯系统的实际应用提供了安全保障。最后给出了该算法在水产品质量追溯系统中的应用方案。
In order to solve such problems as low-level security of traceability code for agricultural products and difficulty to guarantee the traceability code was unique for one product,taking aquatic products as research object,an encryption algorithm of traceability code for aquatic products was put forward.At the base of analysis to coding solution of traceability code and AES encryption algorithm,the aquatic product was coded.Then,this supervision code was compressed and encrypted by an algorithm namely decimal and equal-length to generate the traceability code for aquatic products.The experimental results showed that the proposed algorithm was feasible and reliable.It ensured the deployment security of traceability system owing to the feature of uniqueness and dynamic cipher of traceability code.An example of the application solution of the encryption algorithm in aquatic products traceability system was introduced.
