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.

The exponential growth of Internet of Things (IoT) devices has brought about significant security challenges, particularly due to their limited computational resources and deployment in critical applications such as smart cities, healthcare, and industrial automation. Traditional encryption methods, like AES, are often too resource-intensive for IoT devices, creating a pressing need for lightweight cryptographic solutions that effectively balance security and efficiency. The Tiny encryption Algorithm (TEA) has gained wide adoption for its simplicity and minimal resource requirements, making it a suitable choice for constrained IoT environments. However, TEA’s fixed key scheduling mechanism leaves it vulnerable to cryptanalytic attacks, especially known-plaintext attacks. To address these vulnerabilities, this project introduces an enhanced version of TEA that incorporates a dynamic round key scheduling mechanism, improving its resilience against evolving security threats while preserving its lightweight characteristics. The enhanced TEA algorithm was rigorously evaluated against the original TEA in terms of speed, security effectiveness, and resource efficiency. The results demonstrate significant improvements in adaptability and robustness. Specifically, the enhanced TEA algorithm achieved a markedly stronger avalanche effect of 57.88%, compared to the original TEA’s 49%, highlighting its superior sensitivity to small changes in input. It also exhibited stronger resistance to differential cryptanalysis due to a more complex relationship between plaintext and ciphertext. Additionally, the entropy of the enhanced TEA was measured at 7.6265 bits per byte compared to 6.4380 bits per byte for Original TEA, reflecting a high level of randomness and unpredictability in its cipher text. In terms of overall security and performance, the enhanced TEA algorithm outperformed the original TEA. By offering a secure and efficient encryption solution tailored to the specific limit

With recent advancements in cloud services, the demand for data security during outsourced computations has been increasing. Fully Homomorphic encryption (FHE) offers a promising solution to this demand by enabling the evaluation of arbitrary functions on encrypted data. Over the years, there have been significant developments in using FHE for various applications. One interesting but still incomplete topic is the sorting of encrypted arrays. This task presents several challenges, including the choice of a base sorting algorithm and the need for efficient private comparison methods. In this paper, we present a comprehensive survey of blind sorting, providing a canonical arrangement of previous works. Furthermore, we review the core ideas from key studies, as well as the main challenges and solutions in developing efficient blind sorting algorithms. © 2024 IEEE.

Data security and data privacy are two hot topics in the research world because they cause big damage and are against PDPA laws. Hacker always uses a sophisticated way to hack into the official database. The purpose of this research is to present a method to systematically modify the numerical data to create a mimic database used as a honeypot. An attacker is not aware that he/she is interacting with fabricated data. We proposed a novel algorithm named a "Data Spoofing encryption (DSE) algorithm"in order to normalize data to avoid the attacker's awareness and preserve data privacy. Experimental results indicated that the proposed technique is effective in producing normalized data and in preserving the confidentiality of original data. © 2024 IEEE.

In an attempt to reduce encryption time, we would want to compare the Chipper text-policy-attribute based encryption method with a new lightweight cryptography strategy for secure cloud data sharing. Tools and Methods for Scientific Research: To successfully analyze encryption time for safe data sharing in the cloud, Google Cloud supplies the necessary dataset. Cloud computing frameworks and applications will be explored, planned, and built in this article. Two encryption approaches, Ciphertext-Policy-Attribute Based and Lightweight Cryptography Method, are examined once the database sets are imported. You may think of two main groups into which both algorithms fall. An 80% G-power, a 95% confidence interval, and a 0.05 significance level are all part of the 97 -sample requirement for each dataset. The results may be yours if you can figure out how many milliseconds it takes to encrypt the given inputs. Using the IBM SPSS application, the data is obtained. There is a significant result from the independent sample t-test, as shown by the following: p = 0.000 © 2024 IEEE.

Recently, data-dependent permutations (DDP) that are very suitable for intelligent multimedia and ubiquitous computing systems have been introduced as a new cryptographic primitive for the design of fast encryption systems. The CIKS-128 and CIKS-128H block ciphers are the typical examples of DDP-based encryption algorithms. In this paper. we show that CIKS-128 and CIKS-128H are vulnerable to related-key differential attacks. We first describe how to construct their full-round related-key differential characteristics with high probabilities and then we exploit them to break the full-round CIKS-128 and CIKS-128H with 2(44), and 2(48) data/time complexities, respectively.

Security and confidentiality are one of the main concerns when transmitting multimedia data over the Internet. To deal with the arising security issues, many advanced cryptographic algorithms have been proposed in the literature. The efficiency of these encryption algorithms varies according to the application area in which they are deployed. Although there are many objective evaluation metrics available in the literature to measure the performance of the cryptographic algorithms, however, to the best of our knowledge, no survey or review addresses the quality of the metrics for cryptography algorithms. In this paper, we have presented and analyzed the cryptography algorithms and performance evaluation metrics such as resource utilization measure, quality measure, and security measures to evaluate the security performance of different encryption algorithms for multimedia data. Extensive experiments have been carried out to evaluate the performance of the cryptography algorithms for multimedia data such as images and videos. We have also discussed and analyzed in detail the performance of evaluation measures used to validate the cryptography algorithms. Our findings highlight the strength of different cryptography algorithms and performance evaluation metrics. The analysis is expected to contribute to the design of a new and efficient model for multimedia applications. A detailed analysis of major attacks was also presented for each encryption scheme in tabular form.

Ender Wiggin Played Mafia Wars Too

Games hosted in social networks, gaming servers or mobile phones can be used as massively parallel, but surreptitious processing networks. These grids, and the activities of the unwitting players, can be used for good (such as solving large resource allocation problems or finding improvised explosive devices) or for evil (to allow criminals to gain unauthorized access to a system or break encryption algorithms). Surreptitious processing networks differ from botnets in that no rouge processing elements are present on the user side; instead, the computational payload is outsourced to humans who unknowingly provide partial solutions as they play the game. This approach makes the solution of large computational problems and the recruitment and exploitation of participants easy. This department is part of a special issue on social networking.

INFORMATION FUSION 2020年 62卷 89-109页

作者： Kakkar, Ajay TIET Patiala Punjab India

With the increasing number of emerging robust networks, the challenges to design new security protocols and techniques are never ending. With the enlargement of 5G paradigm, there is a remarkable makeshift in how the distributed devices perform to achieve a common goal. The 5G technology has been significantly revolutionized by the advent of the Internet of Things, and its quick and pervasive evolution. However, it remains imperative that all these devices work in a sequential manner to execute a collective and secure operation. Despite computing being focused around cloud infrastructures in the last two decades, the 5G networks and the huge amount of data it generates is presently inverting this trend, shifting computing power back to where data is generated from. To encompass different autonomous and collaborative systems with functions of data sensing and authentication between such systems in a predictive and adaptive manner is a challenging task. Wireless network design in 5G is expected to emphasize broadly on three facets: security, privacy and energy efficiency. Therefore, this paper investigates the role of various data security and privacy techniques for different generation networks, but emphasis is on 5G. It addresses encryption schemes with the focus on the challenges faced such as side channel and ciphertext attacks, inherent key generation, sharing and distribution, key escrow, analysis of various overheads, and potential techniques, and solutions to address such challenges by leveraging 5G network devices. With the proliferation of ubiquitous computing and wide adoption of hybrid encryption techniques, various attacks will be circumvent in an intelligent manner.
