一种彩色量子图像加密方案
Encryption Scheme of Color Quantum Image
摘要
Abstract
In this paper,a simple encryption scheme for quantum color image is proposed. Firstly,a color image is trans?formed into a quantum superposition state by employing NEQR(novel enhanced quantum representation),where the R,G,B values of every pixel in a 24-bit RGB true color image are represented by 24 single-qubit basic states,and each value has 8 qubits. Then, each of these 24 qubits is randomly rotated π 2 or π radian by employed the controlled rotation gates. After measuring,the whole image does not provide any information. Decryption is the reverse process of encryption. The experimental results on the classical computer show that the proposed encryption scheme has better security.关键词
