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.

In this work, we are going to implement des algorithm on 28-nm Artix-7 FPGA. To achieve high-performance design goal, we are using minimum period, maximum frequency, minimum low pulse, minimum high pulse for different cases of worst-case slack, maximum delay, setup time, hold time, and data skew path. The cases on which analysis is done are like worst-case slack, best-case achievable, timing error, and timing score, which help in differentiating the amount of timing constraint at two different frequencies. We analyzed that in timing analysis, there is maximum of 19.56% of variation in worst-case slack, 0.29% change for best-case achievable, 41.17% change in timing error, and 64.12% change in timing score for two different frequencies. From this work, we also notified the delays during various signals;accordingly, we have designed our own algorithm with strong security encryption.

Effects of iterative block ciphers on quality of experience for Internet Protocol Security enabled voice over IP calls

Voice over IP (VoIP) is the technology used to transport real-time voice over a packet-switched network. This study analyses the effects of encrypted VoIP streams on perceived Quality of Experience (QoE) from a user's perspective. An in-depth analysis on how the transparent nature of encryption can influence the way users perceive the quality of a VoIP call have been investigated by using the E model. A series of experiments have been conducted using a representative sample of modern codecs currently employed for digitising voice, as well as three of the most commonly used iterative block ciphers for encryption (des, 3des, AES). It has been found that the Internet Protocol Security encryption of VoIP strongly relates to the payload sizes and choice of codecs and this relationship has different effects on the overall QoE as measured by the E model, in terms of the way that users perceive the quality of a VoIP call. The main result of this paper is that the default payload shipped with the codecs is not the optimal selection for an increased number of VoIP calls, when encryption is applied and a minimum level of QoE has to be maintained, per call.

A fast CMOS VLSI device is described to execute the Data Encryption Standard (des) algorithm. The device is known as the validated input security device (VISD) since it enables transmitted and received data to be validated through the use of parity checking. The device is directly compatible with most microprocessor families and it is also directly compatible with most DMA controllers. Full or partial parallelism can be used between encryption and input/output communication.

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.

The need for the encryption of the image data is becoming increasingly important as the Internet and Multimedia systems grow in size and popularity. This paper presents a comparison between the application of data encryption standard (des) as a strong encryption algorithm that takes long time to be cracked on two different kinds of images, bitmap and JPEG (joint photographic experts group) images. It shows the results of encryption on both kinds of images, determines the best one for des application to achieve a perfect hiding of image details, and determine the advantages and disadvantages of each case.

The main goal of this paper is to present of security evaluation of block cipher use in wireless network. Information security contributes directly to increase level of trust between users by providing an assurance of confidentiality, integrity, and availability of sensitive information of the network. In this paper, evaluations analysis of RC5, Blowfish and des block cipher algorithms have been done on the basis of block size, numbers of round, and key size of evaluation modeling based on fuzzy logic tool of MA TLAB 2012a. Three metrics are considered for using crypto algorithms for wireless network security. These three algorithms have a variable block size, number of rounds and a variable key size in their structure. Performances of RC5, Blowfish and des algorithms have been evaluated on variables range of metrics of key size, number of rounds, and block size in this paper. Presents the results of evaluation for security level of crypto have shown the security level depending on the structure of algorithm.

This paper presents a novel decentralized interactive architecture for aerial and ground mobile robots cooperation. The aerial mobile robot is used to provide a global coverage during an area inspection, while the ground mobile robot is used to provide a local coverage of ground features. We include a human-in-the-loop to provide waypoints for the ground mobile robot to progress safely in the inspected area. The aerial mobile robot follows continuously the ground mobile robot in order to always keep it in its coverage view.
