“…Rani and others laid the theoretical foundation of information theory, which gave birth to the new science of cryptography [11]. However, during this period, due to the restrictions of various governments, and the application of cryptography was generally limited to the government and military departments, the research on cryptography did not achieve much.…”

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.

“…Also, Table 7 shows the acceptable performance of the proposed method against attacks such as information entropy, differential attack, and correlation coefficient. The present comparison shows the performance of the proposed method against attacks [47][48][49][50]. Increasing the robustness against general attacks, and increasing the key-space are the main advantages of the introduced piecewise map.…”

Many cryptographic schemes have been implemented, using the connection between chaos and cryptography. Substitution box (S-box) is one of the most successful examples of these strategies. However, most S-box design schemes contain a fixed point, which may cause a security issue for cryptographic primitives. In this paper, to achieve a low automatic correlation, a dynamic S-box is constructed based on a piecewise map. Lyapunov exponent has been calculated analytically by using the obtained invariant measure. Then, an image encryption algorithm based on a designated S-box and a trigonometric chaotic map is proposed. Theoretical and experimental results have indicated that the proposed algorithm is included large keyspace, high sensitivity to key, and robust to attacks.

“…3 Security of images become compulsory in the fields like telemedicine, internet communication, military, and multimedia systems. 4 In recent years, the chaos-based encryption models have been widely used in the encryption of images. Chaotic maps are non-linear dynamic systems that have different characteristics like randomness, non-periodicity, and ergodicity.…”

SummaryThe vast technological developments make data transmission more frequent over networks. So, the data needs to be secured and for that reason, there is a requirement to develop an effective encryption model. This article proposes a novel image encryption model using multi‐chaotic maps and blockchain (MCBE). Chaotic maps have been used in encryption models as chaotic maps have the properties of randomness, and non‐periodicity that get utilized in improving the efficiency of an encryption model. Logistic and tent maps have been employed as multi‐chaotic maps to make the encryption process effective in this work. A logistic map has a simple structure and is easily implementable but has some drawbacks like small keyspace. Keyspace and randomness are enhanced by using a tent map along with a logistic map. The proposed MCBE methodology applies to grayscale or colored images having different file formats and sizes. Initially, in the confusion phase, the permutation of the original image is performed based on a random permutation that changes the original image pixel's position. The encryption model applies multi‐chaotic maps, row‐wise and column‐wise in the diffusion phase to promote the efficiency of the encryption model. Finally, blockchain has been implemented using the SHA‐256 hash function to obtain the encrypted image that enhances the security by increasing the keyspace, to resist brute force attacks. The evaluation performance of the MCBE has been analyzed against various attacks namely statistical attacks, differential attacks, NIST randomness test, noise, and cropping attacks. The evaluated keyspace is which has high key sensitivity with a correlation of encrypted images close to 0. Maximum achieved entropy value of 7.9998, SSIM value between original and encrypted images nearby 0 confirms the dissimilarity. The Number of Pixels Change Rate (NPCR) value of 99.62%, and the value of Unified Average Changed Intensity (UACI) value of 33.54% are within the specified standard range. The calculated correlation coefficient, NPCR, and UACI values have been compared with the existing algorithms, and the results show that the proposed MCBE methodology has better performance than the other state‐of‐the‐art methods. The experimental results indicate that the chaotic ranges generated by multi‐chaotic maps and the SHA‐256 hash function improve the keyspace and security of the encryption model confirming the efficacy of the proposed model MCBE.
