AES加密条码在白酒溯源系统中的应用

摘要

To solve encryption and anti-counterfeiting problems of Chinese spirits traceability code, we propose a decimal encryption algorithm ( AES10) .The algorithm, by adjusting four key operations of AES, realises the encryption/decryption taking decimal digit as basic processing unit, and overcomes the drawback of existing decimal encryption algorithm that it can only process the plaintext with specific length.The results of simulation experiment using diffusion rate software show that the proposed algorithm has good security property.Based on AES10, we design an encryption barcodes applicable to the Chinese spirits traceability system and the tracking process of the traceability applying this encryption barcode, and achieve satisfactory effects in traceability encryption and anti-counterfeiting.%为了解决白酒追溯码溯源的加密和防伪问题，提出一种十进制加密算法（ AES10）。该算法通过对AES加密算法四种核心运算的调整，实现了以十进制数为基本处理单位的加密和解密，并克服了现有十进制加密算法只能处理特定长度明文的缺点。扩散率软件仿真实验结果表明，该算法具有较好的安全特性。基于AES10算法，设计了一种适用于白酒溯源系统的加密条码和应用该加密条码的追溯码溯源过程，取得了较好的溯源加密和防伪效果。
