摘要:
为了解决密文图像在公用信道传输过程中容易遭到基于深度神经网络模型攻击的问题,提出一种结合二维压缩感知、新设计的离散分数阶 Chebyshev 混沌映射和空域最低有效位( Least Significant Bit, LSB) 嵌入的视觉有意义图像加密算法。 首先,在明文信息熵的控制下迭代分数阶混沌映射以产生特定的密码流。 其次,采用受控混沌测量矩阵、FAN 变换置乱以及混合扩散策略对明文图像执行二维压缩和加密操作,得到具有统计伪随机性的秘密图像。 然后,通过最低有效位嵌入算法将秘密图像随机地嵌入到非涉密传输介质的各个区域中以生成具有视觉意义的密文图像。 另外,将明文信息熵隐藏到密文图像的透明度通道以实现所提算法安全性和实用性之间的均衡。 最后,仿真结果和理论分析表明,所提加密算法生成的密文图像不但能够抵御多种常见的攻击,还具有不错的视觉安全性。
Abstract:
To solve the problem that the cipher images transmitted in public channel are easily attacked by the deep neural network-basedmodel,a visually meaningful image encryption algorithm by combining the 2D compressive sensing, the newly - designed discretefractional-order Chebyshev chaotic map and spatial least significant bit ( LSB) embedding is proposed. Firstly,the proposed algorithmiterates the fractional-order chaotic map under the control of plaintext information entropy to generate the specific secret key stream. Secondly,the key - controlled chaotic measurement matrixes, FAN transform scrambling and hybrid diffusion strategy are employed toperform the compression and encryption operations on plain image,and the secret image with statistical pseudo-randomness is obtained.Then,the secret image is stochastically embedded into various regions of the non-secret-involved transmission medium by means of theleast significant bit embedding algorithm to generate the visually meaningful cipher image. Additionally,the plaintext entropy is hidden inthe transparency channel of cipher image to achieve the balance between the security and practicability of proposed algorithm.Ultimately,the simulation results and theoretical analyses indicate that the cipher image generated by proposed encryption algorithm hasgood visual security in addition to withstanding various common attacks.
