Abstract: At present, Quick Response (QR) codes are widely used in products, which can provide valuable services such as product traceability, data anti-counterfeiting. However, the source code of QR code is usually publicly available, and the data in QR code is stored in clear text. It cannot be used directly in some specific fields and applications that require confidentiality, so QR code with data encryption is preferred. At present, QR code can be encrypted by Rivest-Shamir-Adleman (RSA) and Advanced Encryption Standard (AES) algorithms. However, those algorithms may not meet the national requirements. In addition, to avoid QR code being copied, dynamic QR code is also indispensable. This paper designs a secure QR code, which uses embedded technology and encryption algorithm SM4 (issued by the State Password Administration of China) to encrypt the information, so it can be embedded in the internet of things equipment to realise convenient secure data transmission.

Keywords: QR code; SM4; embedded system; IoT security.
