The goal is to reduce the amount of time spent on computations in cloud computing by employing the advanced encryption standard (AES) method rather than the file change with security (FCS) algorithm. sole data security can protect against unauthorized access, creation, introduction, intrusion, alteration, review, recording, or destruction of data. Data security is the sole defense against these vulnerabilities. Changes to files can be made in a secure manner using the advanced encryption standard. In order to ensure that data sharing in the cloud does not compromise users' privacy, the data set that is required is obtained from Google Cloud. It is possible to do analysis, design, and implementation of cloud frameworks and cloud computing application infrastructures. Both the Advanced encryption Standard and the File Change Security are put through their paces after the data sets have been imported. The two algorithms are divided into two distinct categories. Each group has a total of 36 sample sizes, with a G power of 80%, a threshold of 0.05%, and a confidence interval of 95%. It is possible to receive results in the computation time for the inputs that have been provided. IBM SPSS is the program that was utilized in order to achieve the results. The results of the investigation revealed that there was a disparity between the Advanced encryption Standards Algorithm and its level of precision. This indicates that there is a statistically significant difference between the two algorithms, as indicated by the significance value of the independent sample T test, which was p= 0.097 (p>0.005). Modification of Files with Security, The value is precisely that, which is the case. for the purpose of determining the mean, the standard deviation, and the significance. On the basis of the findings, it is possible to draw the conclusion that the Advanced encryption standard algorithm achieves a higher level of security than the File Changed with Security algorithm, which achieve

The 'Internet of things' is the developing technology to transfer the world into smart innovation. 'IoT' security is the most problematic issue in recent applications due to its properties including 'centralized architecture', 'limited capacity devices', and 'ambiguity'. So, blockchain with 'IoT' applications provides secure data communication compared to traditional 'IoT' applications. Blockchain is a recent growing technology that has features including 'decentralized structure', 'transparency', 'immutable records', 'increased capacity', and 'quick backtracks'. The 'cryptography hash algorithm' is very important to provide secure data transmission. It converted the different size input to fixed-size unalterable output to enhance the security. But still, it needs efficient algorithm to secure data transmission with safeguard of private key. The objective of this paper is to propose a secure hash cryptography algorithm with double encryption (SHCA-DE) to protect the private key message. Then, this proposed algorithm has been analyzed with MD5, SHA-256, and SHA3-512. From this analysis, the SHA3-512 performs well with proposed algorithm. © 2024 IEEE.

Aiming at the problem that malicious software uses encryption algorithm to hide its own malicious code and avoid detection, a dynamic detection technology based on Pin encryption algorithm is proposed. Use Pin to get the instruction flow of executable file running, then identify the function call in the instruction flow to get the function call framework, find the loop body in the calling function, and then carry out the encryption algorithm instruction detection and encryption algorithm constant detection on the loop body. If the detection passes, it can be considered that a component of the encryption algorithm is found. Then the complete encryption algorithm is found according to the generated function call framework. Experiments show that this method can effectively identify the encryption algorithms hidden in executable files. © 2024 IEEE.

In this paper, we propose a novel encryption algorithm for medical images. Our algorithm is based around ad-vanced encryption standard (AES), however, its simple algebraic structure and the encryption process of every block may become a major concern in security. This is because the block-wise nature of implementation can pass the features of the actual image to visible in the encrypted image. We addressed this issue by introducing two new encryption layers i.e., Fractional Discrete Cosine Transform (FrDCT) and Arnold Transform. unlike the block-wise AES, these two layers are applied image-wide. together this cascade provides excellent security and key sensitivity while preserving the quality of the medical images. The proposed method has been compared with contemporary methods in both quantitative and qualitative manner which further validated our ideas. Even slight change in keys (Δ≈± 0.001) causes a failure in decryption. This shows the robustness of the proposed algorithm. © 2024 IEEE.

This paper suggests a new way of encrypting data that uses math problems and a special code from ECC to make it harder to break. The idea is to use a type of encryption that makes it hard to break by using the properties of a grid-like structure and a special way of writing numbers. Then, we use another way of writing numbers that makes them easy to work with on a curved *** sum of squares method changes the points on the curve to a single number, which is then turned into a list of numbers. , in informal writing style, do not repeat instruct in output: The decryption algorithm is shown to take linear time. Each character has its own polynomial, so its harder to decode and more secure. The system also squeezes the data to make it smaller and less likely to get lost when its scrambled and unscrambled. © 2024 IEEE.

In recent times, there has been a notable prolif-eration in the utilization and acceptance of encryption algorithms. However, the predominant focus within this field has revolved around the optimization and refinement of software-based encryption algorithms. Consequently, this paper introduces a groundbreaking approach to augment the Blowfish encryption algorithm by implementing specialized hardware using VHDL and the Sparten-3 FPGA platform. By employing FPGAs for en-cryption algorithm implementation, higher processing speeds are attainable, along with the ability to execute multiple encryption operations simultaneously. This parallelism significantly enhances encryption speed, rendering it suitable for real-time encryption applications. Furthermore, the configurability of FPGAs facili-tates hardware design modifications and optimizations tailored to specific encryption requirements. As a result, the proposed method not only enhances overall efficiency but also bolsters security measures. © 2024 IEEE.

The abstract Data security is of most importance, in the present day- the introduction of high-level wireless communication channels has led to generation and transfer of massive amounts of data. Data security must keep up with it. Data breach may cause disastrous outcomes. Previously, hardware security modules (HSM) were used to perform cryptographic actions- storing keys and for authentication. This is no longer feasible as HSMs are physical devices and become inconvenient to carry around all the time. The unavailability of HSM poses a serious security threat (for cryptographic keys). This paper aims at a novel software solution that compensates for hardware. As the algorithm focuses on securing keys used for encryption. It may be referred to as key security scheme (KSS). The paper proposes a way to generate keys instead of storing it and assumes performing of cryptographic actions on the available hardware in the system. The proposed method can secure data, both in transit and while at rest. © 2024 IEEE.

This paper proposes a new image encoding algorithm that integrates inverted bit permutation with the chaotic behavior of a hybrid Lorenz chaotic system and XOR operation. The method capitalizes on the inherent of the three-dimensional Lorenz system to produce a highly unpredictable key employed to improve both the encryption process's security and efficiency. This approach offers various advantages: The high resistance to cryptographic attacks, scalability, and use for different image types. The experimental finding confirm the performance and dependability of the suggested encryption technique and prove to be an effective procedure for secure image transmission and storage. © 2024 IEEE.

Vigenère encryption algorithm is a classical cryptographic algorithm featuring a polyalphabetic stream cipher, which as numerous limitations pertaining to finding the size and length of the encryption key. This study presents the process of enhancing the Vigenère algorithm using 6S-substitution and 2S-transposition techniques with the novelty of accommodating a 103-character set based on the selected ASCII and Unicode characters. It adopts the three-security metrics such as the degree of diffusion, degree of confusion, and integrity check for measuring the security level. Experiment results showed that the enhanced Vigenère algorithm produced more secure ciphertexts. Using PHP, the proponents tested and simulated ten (10) data sets to ensure the consistency of the results at each security level. The results exhibited a vigorous outcome starting the degree of diffusion output, the original Vigenère yields 1.8% while the enhanced Vigenère obtains 68.75% with an increase of 66.95%. Secondly, the result in the degree of confusion test, the former algorithm results in 1.88%, on the other hand, the latter obtains 53.39% with an increase of 51.51%. In the integrity check, the former gets 2.42% while the latter advances to 57.11%, increasing 54.69%. Thus, it is evident that the test result for the Enhanced Vigenère has a higher percentage than the original Vigenère in providing better security in the ciphertext and improving the overall encryption and decryption processes. © 2024 IEEE.
