“…The definition of D(i, j) is as follows: if C(i, j) = C'(i, j), then D(i, j) = 1, otherwise, double-precision real number parameter has 10 15 possible values. N 0 is an integer between [1,1000], and there are 10 3 values. Therefore, there are 10 15 × 10 15 × 10 15 × 10 15 × 10 3 ≈ 2 209 key combinations.…”

“…The protection of data security and privacy has become an urgent problem to be solved. Unfortunately, traditional encryption schemes such as AES, DES and RSA are mainly designed for text data so they are not suitable for image security applications [1,2], especially for real-time encryption of big data. Because of the huge amount of image data, high information redundancy and strong correlation urges researchers to seek efficient image encryption algorithms.…”

In the edge computing and network communication environment, important image data need to be transmitted and stored securely. Under the condition of limited computing resources, it is particularly necessary to design effective and fast image encryption algorithms. One-dimensional (1D) chaotic maps provide an effective solution for real-time image encryption, but most 1D chaotic maps have only one parameter and a narrow chaotic interval, which has the disadvantage of security. In this paper, a new compound 1D chaotic map composed of a logistic map and tent map is proposed. The new system has two system parameters and an arbitrarily large chaotic parameter interval, and its chaotic signal is evenly distributed in the whole value space so it can improve the security in the application of information encryption. Furthermore, based on the new chaotic system, a fast image encryption algorithm is proposed. The algorithm takes the image row (column) as the cyclic encryption unit, and the time overhead is greatly reduced compared with the algorithm taking the pixel as the encryption unit. In addition, the mechanism of intermediate key associated with image content is introduced to improve the ability of the algorithm to resist chosen-plaintext attack and differential attack. Experiments show that the proposed image encryption algorithm has obvious speed advantages and good cryptographic performance, showing its excellent application potential in secure network communication.

Faces are widely used in information recognition and other fields. Due to the openness of the Internet, ensuring that face information is not stolen by criminals is a hot issue. The traditional encryption method only encrypts the whole area of the image and ignores some features of the face. This paper proposes a double-encrypted face image encryption algorithm. The contour features of the face are extracted, followed by two rounds of encryption. The first round of encryption algorithm encrypts the identified face image, and the second round of encryption algorithm encrypts the entire image. The encryption algorithm used is scrambling and diffusion at the same time, and the keystream of the cryptosystem is generated by 2D SF-SIMM. The design structure of this cryptosystem increases security, and the attacker needs to crack two rounds of the algorithm to get the original face image.

In this digital world, securing the integrity of the information plays an important role. For a modernized venture, information integrity is requisite for the veracity & competence of employment processes and decision-making. Integrity verification is the one where the information has not been tampered with while it is stored or communicated. Hash function such as SHA-256 is the strongest function, can be used to achieve information integrity. In this paper, a method is proposed where the images are hashed using SHA-256, scrambled using Elliptic Curve Cryptography (ECC), and then added the salted values to generate the secret image. ECC helps achieve high security with a smaller key size. Salting is applied to the scrambled image to increase the randomness. This makes it difficult for the attacker to identify the secret image and reverse back the hashing as hashing is a one-way function. Simulation outcomes of the proposed method have been analyzed by measuring Peak Signal to Noise Ratio (PSNR), Mean Squared Error (MSE), Structural Similarity Index (SSIM), Number of Pixel Change Rate (NPCR), and Unified Average Changing Intensity (UACI). The proposed method is strong against the differential attacks.
