Data Matrix码的AES加密与解密研究

Research of AES encryption and decryption of data matrix barcode

将AES加密算法应用于Data Matrix码的加密,并在.net平台上运用C#语言开发加密Data Matrix生成系统。通过运用条码扫描枪对加密Data Matrix码进行识别,并利用AES解密程序对其所携数据解密验证,最后对该系统生成的80串比特流进行密码学随机性测试。实验结果表明,该系统生成的加密条码在一定程度上提高了Data Matrix码的安全性,能够满足识别速度和可靠性的要求。

The AES algorithm was applied in the encryption of the Data Matrix barcode, and a Data Matrix encryption genera- tor system was developed in C# under the .net platform. The encrypted Data Matrix barcode was recognized by a barcode scanner, then the data in the bareode were decrypted and verified by an AES decryption program,finally, 80 series of bit stream generated by the system were tested for cryptographic randomness. The experimental result shows that the encrypted barcodes generated by the system improve the security of Data Matrix bareode in a certain extent and can meet the demand for the recognition speed and reli- ability.
