Full textAbstract:
This manuscript explores the fusion of two well-known encryption algorithms, the Advanced Encryption Standard (AES) and the Rivest Cipher (RC4), resulting in a novel encryption algorithm called AES-RC4. AES-RC4 is a block cipher that combines the strengths of AES with a variant of RC4 called RC4-GF, developed by ourselves. RC4-GF incorporates additional steps compared to AES, resulting in a more intricate ciphertext generation process.
 The introduction of AES-RC4 brings forth a highly secure encryption technique with increased complexity in the ciphertext compared to traditional AES. By leveraging the combined capabilities of AES and the modified RC4-GF, AES-RC4 offers enhanced encryption strength and improved resistance against cryptographic attacks.

Due to increasing use of image in various field, it is very important to protect the confidential image data from unauthorized access. The design uses the iterative approach with block size of 128 bit and key size of 128, 192 or 256 bit. The numbers of round for key size of 256 bits is 14 , for 128 bits is 10 and for 192 bits is 12.

The rapid advancement of information technology demands enhanced security for data exchange in the digital world. Network security threats can arise from various sources, necessitating techniques to protect information transmitted between interconnected networks. Securing network logs is a critical step in strengthening overall network security. Network logs are records of activities within a computer network, including unauthorized access attempts, user activities, and other key events. This research focuses on developing a network log security system by comparing the performance of the Advanced Encryption Standard (AES) and Twofish algorithms, integrated with the Common Event Format (CEF) for encrypting network logs. Tests were conducted on network log datasets to evaluate system functionality and performance. Results indicate that the AES algorithm performs encryption and decryption faster than Twofish. Across five tests with different file sizes, AES took an average of 2.1386 seconds for encryption, while Twofish required 22.8372 seconds. For decryption, AES averaged 2.451 seconds compared to Twofish’s 26.140 seconds. The file sizes after encryption were similar for both algorithms. Regarding CPU usage, AES demonstrated higher efficiency. The average CPU usage during AES encryption was 0.5558%, whereas Twofish used 23.2904%. For decryption, AES consumed 0.4682% of CPU resources, while Twofish required 13.7598%. These findings confirm that AES is not only faster in both encryption and decryption but also more efficient in terms of CPU usage. This research provides valuable insights for optimizing network log security by integrating standardized log formats, like CEF, with appropriate encryption techniques, helping to safeguard against cyber threats.

Cryptography is a field of study that deals with converting data from a readable to an unreadable format. It can provide secrecy, data integrity, authenticity, and non-repudiation services. Security has become a concern for the community because of the technology’s potential use in numerous sectors of any company, market, agency, or governmental body, information. The cryptosystems ensure that data are transported securely and only authorized individuals have access to it. Deeply encrypted data that cannot be deciphered through cryptanalysis are in high demand right now. There are a variety of encryption algorithms that can guarantee the confidentiality of data. For multimedia data, standard symmetric encryption algorithms (AES) can give superior protection. However, using the symmetric key encryption approach on more complicated multimedia data (mainly photos) may result in a computational issue. To address this issue, the AES has been modified to satisfy the high computing requirements due to the complex mathematical operations in MixColumns transformation, which slow down the encryption process. The modified AES uses bit permutation to replace the MixColumns transformation in AES because it is simple to construct and does not require any complex mathematical computation. This research focuses on using the Modified Advanced Encryption Standard (MAES) algorithm with 128 and 256 bit key sizes to encrypt and decrypt image data. The algorithms were implemented using the Python programming language without complex mathematical computation. By comparing the MAES algorithm with the original AES algorithm, the results showed that the MAES requires less encrypting and decryption time with higher efficiency for all file sizes.

This paper presents modifications on AES algorithm to improve the security of Standard AES, the improving has been done by three modifications. The first modification use key-dependent dynamic S-box (10 S-box) instead of static S-box (1 S-box), that used by Standard AES in order to improve "confusion" properties represented by Byte Substitution layer. The second modification use key-dependent variable values for shifting "state-matrix" rows process instead of fixed values that used by Standard AES in order to improve "diffusion" properties represented by ShiftRows layer. The third modification is by using two keys instead of one key that used by Standard AES, both of them used for encryption and decryption process instead of one key that used by Standard AES in order to improve the general structure and key generation algorithm of AES. The Modified AES tested and evaluated by five scales (Basic Five Statistical Tests, NIST Tests Suite, Encryption Run Time, Brute-Force Attack and Cryptanalytic Attack) to prove the functionality of modifying.

The paper proposes a modification of the Advanced Encryption Standard (AES) to address its high computational requirement steaming from the complex mathematical operations in the MixColumns Transformation which makes the encryption process slow. Bit Permutation was used instead of the MixColumns Transformation since the use of bit permutation in an encryption algorithm achieves efficiency by providing minimum encryption time and memory requirement. Results of the study showed that the modified AES algorithm exhibited faster encryption by 18.47% and faster decryption by 18.77% for text files. The modified AES algorithm also resulted to 16.53% higher avalanche effect compared with the standard AES thus improving the security performance. Application of the modified AES in encrypting images in Cipher Block Chaining mode showed that the modified algorithm also exhibited 16.88% faster encryption and 11.96% decryption compared with the standard AES. Likewise, modifying the algorithm achieved the ideal result in the histogram analysis, information entropy, the correlation coefficient of adjacent pixels to resist statistical attack. The ideal value in number of pixels change rate and unified average change intensity were also achieved making the modified algorithm resistant to differential attack. These results show that modifying AES by using bit permutation to replace MixColumns Transformation was able to address the high computational requirement of the algorithm resulting in a faster and more secure encryption algorithm for text files and images.

Due to the advance in computer eavesdropping and cracker that made them to analysis the way of ciphering in rapid speed way. The development in the computer especially in the rapid processer in the last decade create the breaching of any system is a matter of time. Owing to most of breaching ways are based on analysis of system that requireы to be breached and to try brute force on that system to crack it. However, the lacking of influential processers that are capable of breaching system since earlier processors are limit to number of instructions. It can be done in second, which was not sufficient trying to break the system using brute force. In addition, the time required is far away from getting valuable messages in the time that needed. So, the research gives the focus on performing rapid system for ciphering the information rapidly and changing the ciphering every few milliseconds. The changing of ciphering in every millisecond helps system form preventing the eavesdropping and cracker from imposing brute force on the system and hacking the messages and images. The system that created is based on Advanced Encryption Standard (AES), which is it very best performing algorithm in ciphering and deciphering since it doesn’t need complex mathematical formula. The research is about designing system that capable of performing AES by using high processer designed on Field programmable gate Area (FPGA). The ciphering of AES using FPGA helps minimize the time required to cipher the information. Also, the research will focus on ciphering and deciphering of images by AES using FPGA

Many hacking incidents are linked to work files because most companies work with them. However, a variety of file encryption and decryption methods have been proposed. Existing file encryption/decryption technologies are under threat as hacking technologies advance, necessitating the development of stronger encryption algorithms. Therefore, in this study, we propose a modified advanced encryption standard (AES) algorithm and use quantum computing to encrypt/decrypt AES image files. Because the shift is regular during the AES Shift Row procedure, the change technique led the shift to become irregular when using quantum random walk. Computing resources and speeds were simulated using IBM Qiskit quantum simulators for performance evaluation, whereas encryption performance was assessed using number of pixels change rate (NPCR) and unified average changing intensity (UACI).

Abstract This research proposes an efficient hybridized approach for symmetrical encryption of image files in bitmap formats. Due to the heavy use of lightweight encryption in fields such as military and corporate workplaces, intruders try to intercept communication through illegal means and gain access to classified information. This can result in heavy losses if the leaked image data is misused. The proposed enhances the security and efficiency of one of the most used standard symmetric algorithms, Advanced Encryption Standard (AES). In the proposed method, the AES architecture has been modified using a less intensive algorithm, Data Encryption Standard (DES). DES carries a sub-process of permuting data columns rather than the AES’s mixing feature. The proposed algorithm is analyzed using a set of 16 bitmap images of varying memory sizes and resolutions. The effectiveness of the algorithm is evaluated solely in terms of perceptual invisibility as per the main objective of the research.

E-Voting is an election that uses information technology facilities as well as electronic devices where part or all of the process is done digitally. The electoral process by means of E-voting can help the counting process faster and costs less than the conventional electoral process. However, this electronic-based election is prone to manipulation, therefore it requires protection of the system. In this study, AES and CSRF algorithms were implemented to increase security in the E-Voting application. The election is limited to the election of the executive mayor / regent. This study uses Acunetix software to test the level of security. In testing, four versions of the website were made, namely: the website without AES and CSRF, the website only with AES, the website only CSRF and the website using AES and CSRF. The test results on the website with AES and CSRF show a satisfactory increase in security, only one medium level application vulnerability warning and two low level application vulnerability warnings. Test results with Acunetix on websites without AES and CSRF received seven medium warnings and eleven low warnings. The CSRF test results only get two low warnings but the number of data scans is only a few. The AES test results only get four medium warnings and one warning. Thus, the application of the AES algorithm can increase the level of security of the E-Voting system

In this work, the design and implementation of secured communication in a wireless network was achieved. The design was accomplished by using a Modified Advance Encryption Standard (MAES) algorithm and visual studio. A byte rotation technique was used to modify the Advance encryption standard in order to improve security of files over a wireless network. In the work, files were encrypted such that if they fall in the hands of unauthorized users, their content remains secured because MAES was used to encrypt them. Binary files of different formats and sizes were used to test the design, and file encryption and decryption without loss in fidelity was achieved using the MAES algorithm. Fifteen different file formats with different sizes were used to test the system and results obtained were compare with the Advanced Encryption Standard (AES) algorithm, MAES was equally very efficient in speed. Hence, byte rotation used to modify AES does not only improve security but equally very fast. The research therefore recommend amongst other things the usage of MAES for securing files.

(Cryptography Advanced Encryption Standard (AES) for File Document Encryption). Advanced Encryption Standard (AES) is a cryptographic algorithms as a standard symmetric key encryption algorithm that used in current time. AES 128 has 1 blok plaintext with 128 bit sized, where in the process of cryptographic algorithms, first the plaintext is converted into hexadecimal-sized 4 x 4 matrices called the state, where each element of state has 1 byte size. The process of encryption on AES is the transformation towards the state repeatedly in the 10th round. Each round of AES requires one key result of the key generation using 2 basic transformation, i.e. substitution and transformation. AES encryption using 4 transformation by the following sequence: subbytes, shiftrows, mixcolumns, and addroundkey. On the other hand, the process of decryption is using the inverse of all the basic transformation of AES algorithm, except addroundkey. Therefore, the sequence of transformation on the decription is invshiftrows, invsubbytes, invmixcolumns, and addroundkey. In the data text, the encryption process is initiated with convertion the data text into ASCII code in hexadecimal numbers that are molded into the matrix 4 x 4 bytes. Next, do some basic transformation such as subbytes, shiftrows, mixcolumns, and addroundkey. However, when performing the transformation, the processed data on every trasformation is in the form of binary data obtained from the hexadecimal matrix. AES 128 bit cryptography have room 2128 keys which is a tremendous value and is considered secure to use to avoid the brute force attack.

Data security refers to the confidentiality of information exchanged, especially when the data is on a computer network that is connected to other networks. Of course, this is risky when irresponsible individuals gain access to confidential or valuable information. To avoid the undesired possibility of damage or loss leading to significant material loss. To solve this problem, you need a security system that helps encrypt and decrypt data files. Cryptography is the study of cryptography in which plaintext is encrypted with an encryption key and transformed into a script that is difficult for others to read without the decryption key. Cipher sare class ified intot wotypes. classic and modern. Classical encryption works in character mode using the alphabet (A-Z) and the algorithms used are simple enough to easily break the ciphertext, while modern algorithms use ASCII (American Standard Code for Information It is formed using binary bits (0's and 1's) derived from the Interchange. Creating a key is so complicated that knowing the key makes it difficult to guess the ciphertext. In this study, we create a cryptographic application that uses the 128-bit Advanced Encryption Standard (AES) encryption algorithm. The programming language is PHP and uses MySQL as the web application print and database. Files uploaded for encryption are stored in the database. It is expected that students will be able to maintain the security of their file data with the help of this application.

In an era where data security remains paramount, modern cryptographic systems are essential to safeguarding sensitive information. The Elliptical Advanced Encryption Standard (E-AES) is a cutting-edge approach that leverages the strengths of traditional AES and elliptic curve cryptography (ECC). While AES is celebrated for its robust encryption capabilities, it suffers from increased computational overhead in resource-constrained environments. Similarly, ECC offers lightweight encryption with high security but faces challenges with scalability and data throughput. Combining these methodologies addresses these limitations, creating a hybrid algorithm that achieves both efficiency and security. The proposed E-AES employs elliptic curve-based key exchange for secure, lightweight key distribution, coupled with AES for high-throughput data encryption. Experimental evaluations demonstrate a significant reduction in encryption time (15%) and decryption time (18%), alongside enhanced security with an average entropy score of 7.96 out of 8, compared to traditional AES systems. The approach also reduces computational overhead by 20%, making it suitable for resource-limited applications like IoT and mobile devices. This hybrid encryption algorithm ensures secure communication by mitigating potential vulnerabilities associated with single-algorithm systems. E-AES thus represents a robust, scalable, and computationally efficient solution for modern secure data communication systems.

Data security is essential. Educational question banks at vocational high schools (SMK) contain confidential information that could be misused if not properly secured. This research aims to ensure students question bank data and develop a responsive web platform for Pusdikhubad Cimahi Vocational School by implementing the integration of the Advanced Encryption Standard (AES) and Rivest Shamir Adleman (RSA) cryptographic algorithms through the encryption and decryption process. AES is a symmetric key cryptography algorithm, while RSA is an encryption algorithm based on using public keys to encrypt the keys required by AES-256. The integration of these two algorithms aims to ensure data confidentiality, prevent manipulation, and facilitate access to exam materials by authorized parties. This research shows that the process of encrypting and decrypting question data using a combination of RSA and AES was successfully carried out on the question bank system. Avalanche Effect testing shows that the RSA and AES 256-bit encryption has an Avalanche Effect level of 49.99%. Apart from that, the system feasibility test using black box testing results shows that the SIFILE system has a percentage level of 100%.

The cryptographic techniques often stored on hardware devices are easy to hack as the keys required for encrypting or decrypting the data must be stored along with the architecture on hardware. This increases a necessity to develop an alternative to key-storing problem. As a solution, a physical unclonable function is proposed. Physical Unclonable Function are circuits which are made up of simple logic devices which are easy to analyse, but it is hard to predict the outputs of such systems. These circuits will be used for key generation for the Advanced Encryption Standard algorithm for data hiding, as part of the proposed project work.

Full textAbstract:
The wide acceptability of Advanced Encryption Standard (AES) as the most efficient of all of the symmetric cryptographic techniques has further opened it up to more attacks. Efforts that were aimed at securing information while using AES is still being undermined by the activities of attackers This has further necessitated the need for researchers to come up with ways of enhancing the strength of AES. This article presents an enhanced AES algorithm that was achieved by modifying its SubBytes and ShiftRows transformations. The SubBytes transformation is modified to be round key dependent, while the ShiftRows transformation is randomized. The rationale behind the modification is to make the two transformations round key dependent, so that a single bit change in the key will produce a significant change in the cipher text. The conventional and modified AES algorithms are both implemented and evaluated in terms avalanche effect and execution time. The modified AES algorithm achieved an avalanche effect of 57.81% as compared to 50.78 recorded with the conventional AES. However, with 16, 32, 64, and 128 plain text bytes, the modified AES recorded an execution time of 0.18, 0.31, 0.46, and 0.59 ms, respectively. This is slightly higher than the results obtained with the conventional AES. Though a slightly higher execution time in milliseconds was recorded with the modified AES, the improved encryption and decryption strength via the avalanche effects measured is a desirable feat.

Summary In this article, we formalize the Advanced Encryption Standard (AES). AES, which is the most widely used symmetric cryptosystem in the world, is a block cipher that was selected by the National Institute of Standards and Technology (NIST) as an official Federal Information Processing Standard for the United States in 2001 [12]. AES is the successor to DES [13], which was formerly the most widely used symmetric cryptosystem in the world. We formalize the AES algorithm according to [12]. We then verify the correctness of the formalized algorithm that the ciphertext encoded by the AES algorithm can be decoded uniquely by the same key. Please note the following points about this formalization: the AES round process is composed of the SubBytes, ShiftRows, MixColumns, and AddRoundKey transformations (see [12]). In this formalization, the SubBytes and MixColumns transformations are given as permutations, because it is necessary to treat the finite field GF(28) for those transformations. The formalization of AES that considers the finite field GF(28) is formalized by the future article.

<p><em>AES is a cryptographic computation intended to work on 128bit, 192bit, and 256bit message blocks. The four main calculation procedures consist of a process (ShiftRows) and three substitution processes (SubBytes, MixColumns, and AddRoundKey). The AES encryption procedure is intended to perform encryption confidentially with a non-linear level of security with time complexity as effectively as possible, using a light change procedure in its implementation. On the other hand, the inverse of this procedure has low effectiveness, so the AES description procedure is slow. By examining the calculations, it was found that AES has complexity in the O(n) level for both encryption and decryption procedures. From a security check, AES has a very high level of security. From the speed correlation test results, it can be concluded that AES has a high level of effectiveness. Meanwhile, through testing encryption versus description, it can be understood that from timeliness, encryption is not equivalent to description, with the effectiveness of description being quite low.</em></p>

Full textAbstract:
Cryptography focuses on ensuring the security and integrity of data. Initially, various algorithms were developed for encoding and decoding, but many proved inadequate for protecting large and sensitive datasets. This led to the creation of AES, a robust standard for data encryption and decryption. Originally designed to safeguard highly confidential information, AES has since been adopted widely in networking applications to secure data. It primarily aims to protect sensitive information and is also utilized in network backends to bolster security. AES operates with 16-byte blocks and supports key sizes ranging from 128 to 256 bits. The choice of Verilog over standard VHDL is due to its reduced operational time and lower propagation delays in data encoding and decoding compared to other hardware description languages. Before AES, DES served as the encryption standard, but its limitation of a fixed 56-bit key size posed significant security risks. AES addresses this issue by allowing variable key sizes for enhanced flexibility. Index Terms—Advanced Encryption Standard, Input text, Cipher text, Verilog.

Cryptography is about protecting the data from third parties or from public to read confidential data. Cryptography mainly focuses on encrypting the data or we can say converting the data and decrypting the actual data or we can say reconverting the data by different methods. These encryption and decryption methods are based on mathematical theories and are implemented by computer science practices. But as cryptography progressed ways were found to decode the secured data and view actual data. This was also done by the use of mathematical theories and computer science practices. Popular algorithms which are used in today’s world are, AES (Advance Encryption Standard), Blowfish, DES (Data Encryption Standard), T-DES (Triple Data Encryption Standard), etc. Some of the previously known algorithms were RSA (Rivest–Shamir–Adleman), ECC (Elliptic curve cryptography), etc. These algorithms have their own advantages and drawbacks. But as people were progressing more in breaking them down, these algorithms were supported by digital signatures or hash done by different algorithms like MD5, SHA, etc. By these means data integrity, data confidentiality, and authentication of data are maintained. But as the things are progressing it seems that new advancements are always needed in the field of cryptography to keep the data secure.

Mobile Ad Hoc network (MANET) is a connection of mobile nodes that are joined together to communicate and share information using a wireless link.Some of the MANET in use include mobile smart phones, laptops, personal digital assistant (PDAs), among others.However, MANET has been known for the major challenge of being vulnerable to malicious attacks within the network. One of the techniques which have been used by several research works is the cryptographic approach using advanced encryption technique (AES). AES has been found suitable in the MANET domain because it does not take much space in mobile nodes which are known for their limited space resources. But one of the challenges facing AES which has not been given much attention is the optimal generation of its secret keys. So, therefore, this research work presents a symmetric cryptography technique by developing a model for the optimal generation of secret keys in AES using the linear function mayfly AES (LFM-AES) algorithm. The developed model was simulated in MATLAB 2020 programming environment. LFM-AES was compared with mayfly-AES, particle swarm optimization AES (PSO-AES) using encryption time, computational time, encryption throughput, and mean square error. The simulation results showed that LFM-AES has lower encryption, computational, mean square error, and higher encryption throughput.
