摘要
为了防止二维码所含的信息被篡改或者窃取,设计了一种基于嵌入式的二维码加密系统。通过将随机生成器产生的128位初始密钥与AES加密算法相结合的方法对二维码信息进行加密,随后将密文通过QR编码,得到信息加密后的二维码,最后采用友善之臂的Tiny4412开发平台来实现构建该二维码加密系统。经测试结果表明,该二维码加密系统提高了QR二维码信息的安全性并增强了二维码的防伪性。
In order to prevent the two-dimensional code information from being tampered or stolen, a two-dimensional code encryption system based on embedded system is designed in this paper. The two-dimensional code information is encrypted by combining the 128-bit initial keys generated by the random generator with the AES encryption algorithm, then the ciphertext is encrypted by the QR code to generate the two-dimensional code, and finally the arm Tiny4412 development platform is used to build the two-dimensional code encryption system. The test results show that this design improves the security of QR code information and enhances its security performance.
