Abstract

QR code is widely used in many scenarios including online transactions, warehousing, manufacturing and authentication. However, in the era of continuous development of quantum technology, the traditional QR code encryption method has low security in front of quantum technology, and information is easy to be stolen and forged. In response to the above problems, we consider combining post-quantum cryptography with QR code. In this work, we propose a quantum-safe, anti-counterfeiting and tamper-proof QR code based on lattice-based cryptography. The proposed QR code technique features two advantages: (a) it can be easily deployed on mobile phone apps and the verification is computationally efficient; (b) it is safe under quantum attacks and impossible to be forged and imitated in plausible quantum future.
