Yingzhen Yu · Computer and Digital Engineering · 2014
With the wide application of two-dimensional code,two-dimensional code encryption technology has attracted more and more attention.QR(Quick Response)two-dimensional code is a widely used two-dimensional code.The different stages of the implementation procedure have different characteristics.This paper presents a multilevel fusion encryption algorithm based on QR code,greatly improved the encryption intensity of QR code by using DES and fixed keys RC4 encryption in different stages.This algorithm does not significantly increase the length and the processing time of QR code.The experimental data show the validity of the algorithm.
