In view of the simple keys, time-consuming in encryption and decryption process and the loss of original function characteristics in encrypted image QR two-dimensional code, we adobe a kind of encryption method of QR code based on ECA state ring. In this method, the simple structure, highly parallel of elementary cellular automaton is being used. Operating each pixel point on the quick response code except which can express QR code function information. The simulation results show that the method is faster than two kinds of typical QR code encryption method, and the encrypted image can preserve the original QR code function information, while the safety coefficient is very similar.
