“…Chaos is widely used and highly respected in the field of image encryption due to its unpredictability, pseudorandomness, and high sensitivity to initial values. At present, a variety of encryption methods have been proposed, including quantum cipher [13][14][15], bit-level encryption [16][17][18], discrete wavelet transform [19][20][21], thumbnail-preserving encryption [22][23][24], biological coding [25][26][27], discrete cosine transform [28][29][30], Fourier transform [31][32][33], chaos theory [34][35][36][37][38][39][40] and so on [41][42][43][44][45].…”

Most of the existing spatial domain image encryption techniques suffer from the difficulty of resisting cryptographic attacks. For this reason, this paper proposes a frequency-domain based digital image encryption scheme by combining Integer Wavelet Transform (IWT), three-dimensional S-box and chaotic system. Firstly, the plaintext image is decomposed into different frequency subbands by IWT to map the digital image from spatial domain to frequency domain. Second, the plaintext hash value is selected as the dynamic key, and dynamic chaotic pseudo-random sequences with associations are generated, which are used for the encryption of each module respectively. Then, a three-dimensional S-box is designed to encrypt the information-rich low-frequency information using ``bit-permutation three-dimensional S-box substitution ciphertext interleaved diffusion'', while the high-frequency information is encrypted using a lightweight ``XOR-row column permutation'' operation. Finally, the secure ciphertext for public channel transmission is obtained by the reconstruction method. the scheme of this paper, the frequency domain transformation is implemented through IWT, which enhances the ability to resist attacks. In addition, each encryption module employs a closed-loop feedback mechanism, thus the algorithm has the ability to resist plaintext attacks. Theoretical analysis and empirical results show that the algorithm has excellent numerical statistical analysis results, These findings confirm that the proposed method exhibits good confusion, diffusion, and avalanche effects and can withstand a variety of popular cryptographic attacks. Given that frequency domain picture encryption is a preferred high-security technique for safeguarding the privacy of digital photographs, it is a workable solution for practical applications.

Observing the 3D (three-dimensional) surface vibration in hundred MHz is challenging due to low speed of CCD/CMOS camera. In order to obtain the ultrafast dynamic 3D shape information, a compressed ultrafast 3D imaging framework based on interferometry is proposed in this paper. Based on this imaging framework, an reconstruction method combining Plug and Play-Fast Flexible Denoising Network (PNP-FFDNET) is developed to recover high resolution interference fringe patterns and the corresponding 3D information. The simulation results show that the proposed method can observe the dynamic processes of the anti-phase vibration and the in-phase vibration of the crystal oscillator, therefore the dynamic 3D model is established. The proposed method outperforms other reconstruction methods in terms of average Peak Signal to Noise Ratio (PSNR) and Structural Similarity (SSIM) in recovery the ultrafast dynamic 3D surface.

“…Therefore, the utilization of image encryption techniques can effectively prevent important data from being leaked during transmission. Many encryption methods have been proposed, such as quantum cipher [1][2][3], thumbnail-preserving encryption [4][5][6][7], biological coding [8][9][10], discrete wavelet transform [11][12][13], discrete cosine transform [14][15][16], bit-level encryption [17][18][19], Fourier transform [20][21][22], chaos theory [23][24][25], and so on [26][27][28]. Moreover, the unpredictability, pseudo-randomness, and high sensitivity to initial values of chaos make it the most effective and widely used approach for image encryption algorithms.…”

This paper proposes a dynamic RNA-encoded color image encryption scheme based on a chain feedback structure. Firstly, the color pure image is decomposed into red, green, and blue components, and then a chaotic sequence based on plaintext association is introduced to encrypt the red component. Secondly, the intermediate ciphertext is obtained by diffusion after encryption by bit-level permutation, RNA dynamic encoding, RNA dynamic operation rules, and RNA dynamic decoding. Finally, to enhance the security of the image cryptosystem, the green and blue components of the image are repeatedly encrypted using the chain encryption mechanism associated with the intermediate ciphertext to obtain the color cryptographic image. In this paper, a 2D-SFHM chaotic system is used to provide pseudo-random chaotic sequences, and its initial key is calculated by combining the hash function and external parameters of the image, and the one-time ciphertext encryption strategy causes the proposed encryption to effectively resist cryptographic attacks. Experimental results and security analysis show that our encryption algorithm has excellent encryption effects and security performance against various typical attacks.
