Generating random values become increasingly desirable due to its advantages. In this paper, a novel pseudo-random number generator is proposed based on a hyperchaotic system and the des algorithm, with the goal of solving the limitations of many existing generators, such as predictability and inefficiency. The main contribution is the use of the des algorithm, which is no longer used as an encryption algorithm, as a random generator, allowing the existing algorithm to be exploited in many applications. The hyperchaotic system has good statistical properties and random bifurcation, which means that the hackers cannot predict these sequences. The random values are used to produce both the initial key and input for the des algorithm and the results of the des algorithm are considered as a pseudo-random sequence. This ensures that both the key and the input of the des algorithm are random, which increases the security of the des algorithm. In addition, both the des encryption and decryption algorithms are used in the generator, relying on the hyperchaotic system to choose in each iteration, which means that the hackers cannot determine which algorithm is used to produce the pseudo-random sequence. Experimental and analysis results show that the proposed generator has good random characteristics and passes several statistical tests, such as the NIST tests. Moreover, the proposed generator is tested in cryptography, using stream cipher to encrypt images. The results show that the encrypted images can resist several attacks such as histograms, differential attacks, correlation analysis, and entropy.

The confidentiality of accounting data is crucial for the security and trade secrets of enterprises. The aim of this study is to explore an accounting data encryption processing system that improves the des algorithm, enhancing the efficiency and security of data encryption processing. This article optimized the system architecture and algorithm design by introducing safer AES (Advanced Encryption Standard) algorithms, and combined hardware to accelerate the technological process. The experimental results showed that under the same amount of data, the AES algorithm reduced the encryption time by an average of 40% compared to the des algorithm. This indicated the need to further strengthen key management. It needs to establish a data backup and recovery mechanism, and strengthen security training and awareness enhancement to improve the security performance of the accounting data encryption processing system of des algorithm. These improvements would provide enterprises with more reliable and effective accounting data protection solutions, ensuring the confidentiality and integrity of accounting data. © 2023 IEEE.

To ensure the safe operation of power system, this paper studies two technologies of data encryption and digital signature, and designs a real-time data encryption system based on des algorithm, which improves the security of data network communication. The real-time data encryption system of power system is optimized by the hybrid encryption system based on des algorithm. The real-time data encryption of power system adopts triple des algorithm, and double des encryption algorithm of RSA algorithm to ensure the security of triple des encryption key, which solves the problem of real-time data encryption management of power system.

The more and more developed network has caused more and more impact on people's life and work, providing convenient channels for people's information exchange, and then improving people's living and working conditions. However, when data is transmitted through the network, there are hidden security risks, especially important accounting data. Once intercepted and used by criminals, it may cause serious harm to the owner of the data. Based on the above background, the purpose of this article is to study the use of the des algorithm to encrypt accounting data in a computing environment. This paper proposes an improved quantum genetic algorithm and applies it to the S-box design of the des algorithm, which improves the non-linearity of the S-box, reduces the differential uniformity, and enhances the security of the des algorithm. This improved des algorithm reduces the number of iterations by increasing the key length and iterative processing using a two-round function, which further increases the security of the algorithm and improves the operation speed of the encryption process. It is found that the 64 ciphertexts of the des algorithm and the number of changed bits compared to the original ciphertext fluctuates around 32 bits, which explains the problems that should be paid attention to when using the des algorithm to encrypt accounting data. The validity of key characters should be guaranteed to prevent key loss or leakage. Shorter data encryption regular solution.

The Internet is developing rapidly, which leads to a sharp increase in information transmitted by the network. Moreover, people have a higher demand for encrypting meetings and encrypting information transmission. Currently, the data encryption technologies used in network transmission mainly include symmetric encryption algorithms, asymmetric encryption algorithms, virtual network encryption technology, SSL protocol encryption, etc. However, the widely used symmetric encryption algorithm has some problems, such as complex distribution and complicated management of keys, while the asymmetric encryption algorithm generally has the disadvantages of slow encryption and decryption speed. The research and analysis of the typical symmetric encryption algorithm des and asymmetric encryption algorithm RSA are studied to address this issue. This paper puts forward mixed cryptogram arithmetic of des and RSA. The principle of the algorithm is that the sender encrypts the key of des with RSA's public key and then encrypts the plaintext with the new longer key by des. The receiver can decrypt the encrypted key and ciphertext to obtain plaintext. The advantage of this hybrid algorithm is that RSA only needs to encrypt the short key of des. Therefore, the encryption speed is improved greatly, and a longer new key is obtained, which makes the encryption result of des more secure and reliable. The hybrid algorithm shows good performance through the code implementation and analysis of the results. Not only the encryption speed is fast, but the security is also guaranteed, and it has a favorable application prospect in digital signature and other fields. © 2023 IEEE.

Anti-attacks encryption algorithm based on DNA computing and data encryption standard

Data Encryption Standard (des) is the first 56-bits secret-key standard that is widely used as a symmetric-key 64-bits block encryption/decryption algorithm. Unfortunately, the rapid increase in computing power makes it possible to find the required bits combination of the secret-key in a short time. Due to the promising trends of Deoxyribonucleic Acid (DNA) in cryp-tography, this paper presents a des-DNA based symmetric-key block encryption/decryption algo-rithm called iEncrypt. iEncrypt has two versions, each of them uses a 64-nucleotides secret-key that makes the secret-key of the proposed algorithm intractable as 128-bits secret-key. The experimental works show that the two versions of iEncrypt are intractable against brute force attacks. Moreover, the reduced version of the proposed algorithm, to 4-rounds, shows the intractability of the first ver-sion against differential cryptanalysis attacks in addition to the invisibility of attacking the second version. Plain images data are used as one of the rich characteristics data in the statistical evalua-tion. Statistically, the encrypted images confirm the intractability of both versions of the proposed algorithm.(c) 2022 THE AUTHORS.

In order to overcome the problems of poor data security, low integrity and long storage time of traditional methods, this paper proposes a dynamic and secure storage method of enterprise financial data based on cloud platform. Firstly, the absolute correlation degree of the data in the financial database is calculated by using the grey correlation analysis method, and the data mining and clustering are carried out according to the results of the absolute correlation degree calculation. Then, the des algorithm is used to encrypt the clustering results of financial data and remove redundant data. Finally, according to the cloud platform access time length, access frequency, and the relationship between enterprise financial datasets, the data dynamic security storage is achieved. Experimental results show that this method can encrypt all data, the average integrity of the storage results is 9.7, the average storage time is 0.51 s, and the practical application effect is good.
