“…As well as a study by researcher Ashwak alabaichi, the study includes three phases: Design, implementation and verification In the first phase, 3D Dynamic S-Box, Dynamic P-box and F-Function were designed. The second stage is to implement a key to expand, encrypt and decrypt the data, as for verification, it includes evaluating the output of the new design using a random statistical test and coding analysis [16]. The aim of this research by researchers Vaibhav Poonia and Dr. Narendra Singh Yadav aims to improve and evaluate the Blowfish algorithm based on various parameters such as encryption quality, correlation coefficients, key sensitivity testing, and output file size.…”

“…As a result, blowfish-MD5 has shown to be more efficient than the previous approach. 16 The statistical test of randomness on the Blowfish Block Cipher is presented in this study. The results also revealed that the ECB mode of the Blowfish method is ineffective for images and text files with long sequences of identical bytes.…”

Abstract. Security is the study of encryption and decryption, data hiding, potential attacks, and performance evaluation. Many algorithms perform this purpose. Blowfish is a symmetric block cipher that uses the Feistel network. Although several works employed the Blowfish algorithm for the security of the cloud, there is still no article that lists previous studies. Cloud computing is the transmission of computer services such as servers, storage, databases, networking, software, analytics, and intelligence through the Internet ("the cloud") in order to provide faster innovation, more flexible resources, and cost savings. The most common issue with cloud computing is information security, privacy, confidentiality, and how the cloud provider ensures these services. This paper includes a survey of most previous works that were concerned with using the Blowfish algorithm in achieving cloud security

“…Other studies improved key generation of Blowfish to minimize the time required to produce subkeys [23]- [26]. For all studies involving the production of subkeys, the generation of elements achieved reduced time complexity though approaches used was entirely different from that of the original algorithm.…”

Cryptography guarantees security in communication through encryption. This paper proposed a modified Blowfish encryption that uses 128-bit block size and 128-bit key to comply with minimum requirements as an encryption standard. The modification retained the original structure for easy migration but utilized two S-boxes to save memory. A derivation was added to prevent symmetry. The algorithm’s performance was evaluated using time, and avalanche. Upon testing, the modified blowfish is slower with key, encryption, and decryption average of 26.99ms, 1651.83ms, and 2765.04ms compared to blowfish with 21.65ms, 1297.76ms and 2176.59ms due to block size difference. Applying 128-bit block size increases security by decreasing the chances of having duplicate blocks that may leak information. The modified Blowfish is faster compared to Twofish with an encryption and decryption average time of 2418.08ms and 4002.70ms. The added derivation improved the avalanche of the modified blowfish. Blowfish achieved 47.14% while modified Blowfish attained 52.86%.
