“…e cryptosystems used before this all belong to the private key cryptosystem, that is, the sender and the receiver of information use the same or similar key, and the key needs to be negotiated and transmitted before information is transmitted, as shown in Figure 1 for the data encryption system model [14,15]. Subsequently, the rst practical public key cryptosystem, RSA, was proposed.…”

In order to solve the practical problem that the security of computer network information cannot be guaranteed, which seriously affects the network performance, the author proposes a public key data encryption system based on PKI. The system proposed by the author is based on the public key cryptographic algorithm RSA, including implementation of data encryption and digital signature and key distribution, an improved RSA algorithm is proposed for the slow speed of RSA. The result obtained is as follows: after reasonable selection of parameters and the use of optimized algorithms (also known as combined algorithms), the RSA algorithm is about 1.0% to 2% more efficient than the traditional algorithm, to a certain extent, the operation efficiency of the RSA algorithm is improved, and the purpose of improving the RSA algorithm is achieved. It is proved that the public key data encryption system is of great significance for modern computer network information encryption and maintaining a green and secure network environment.

“…The Peak Signal to Noise Ratio (PSNR) was calculated for all the input images and their corresponding decrypted images to tabulate the quality of the decryption algorithm, given in Table 9 . The tabulation also compared the proposed work with ‘state of the art; techniques [ 41 , 45 , 46 , 47 ], and shows that the values obtained were approximately equal to the existing methods. Figure 19 shows the 6.25%, 25% and 50% cropping attack analysis on the Lena test image.…”

With the advancement of technology worldwide, security is essential for online information and data. This research work proposes a novel image encryption method based on combined chaotic maps, Halton sequence, five-dimension (5D) Hyper-Chaotic System and Deoxyribonucleic Acid (DNA) encoding. Halton sequence is a known low-discrepancy sequence having uniform distribution in space for application in numerical methods. In the proposed work, we derived a new chaotic map (HaLT map) by combining chaotic maps and Halton sequence to scramble images for cryptography applications. First level scrambling was done by using the HaLT map along with a modified quantization unit. In addition, the scrambled image underwent inter- and intra-bit scrambling for enhanced security. Hash values of the original and scrambled image were used for initial conditions to generate a 5D hyper-chaotic map. Since a 5D chaotic map has complex dynamic behavior, it could be used to generate random sequences for image diffusion. Further, DNA level permutation and pixel diffusion was applied. Seven DNA operators, i.e., ADD, SUB, MUL, XOR, XNOR, Right-Shift and Left-Shift, were used for pixel diffusion. The simulation results showed that the proposed image encryption method was fast and provided better encryption compared to ‘state of the art’ techniques. Furthermore, it resisted various attacks.

“…This paper uses information entropy to quantitatively compare the randomness of images before and after encryption. The larger the information entropy value, the stronger the randomness of the information distribution of the image and the better the encryption effect [ 22 ]. The ideal information entropy of the ciphertext image is eight, indicating that the information distribution of the image is completely random.…”

Information security has become a focal topic in the information and digital age. How to realize secure transmission and the secure storage of image data is a major research focus of information security. Aiming at this hot topic, in order to improve the security of image data transmission, this paper proposes an image encryption algorithm based on improved Arnold transform and a chaotic pulse-coupled neural network. Firstly, the oscillatory reset voltage is introduced into the uncoupled impulse neural network, which makes the uncoupled impulse neural network exhibit chaotic characteristics. The chaotic sequence is generated by multiple iterations of the chaotic pulse-coupled neural network, and then the image is pre-encrypted by XOR operation with the generated chaotic sequence. Secondly, using the improved Arnold transform, the pre-encrypted image is scrambled to further improve the scrambling degree and encryption effect of the pre-encrypted image so as to obtain the final ciphertext image. Finally, the security analysis and experimental simulation of the encrypted image are carried out. The results of quantitative evaluation show that the proposed algorithm has a better encryption effect than the partial encryption algorithm. The algorithm is highly sensitive to keys and plaintexts, has a large key space, and can effectively resist differential attacks and attacks such as noise and clipping.
