“…This method is useful for continuous communications over time, such as video sequences and VOIP calls. [35] propose an algorithm for password security in online authentication, where the entered password is stored in a remote database. Using the SHA-3 hash function, the system must hash the password.…”

In this work, we propose a novel approach to enhancing the security of passwords before storing them in databases. Our method utilizes Braille transformation to encrypt the password after generating the corresponding hash. The hash is divided into multiple blocks, each representing a character treated as a transformation unit. Each character is then associated with its corresponding Braille code, which consists of 6 digits. To further enhance security, we randomly replace each occurrence of "0" in the generated string with one of the digits 7, 8, or 9. The final string, six times larger than the original hash, is then stored in the database. To evaluate our approach, we conducted several experiments and comparisons. The results demonstrate that Braille transformation is resistant to brute-force attacks, statistical attacks, and differential attacks. These results were justified using various evaluation criteria, such as execution time and memory space occupied. Braille transformation is susceptible to any modification made to the hash or the generated string, further reinforcing its security. Our Braille-based approach offers an effective solution to strengthen the security of database passwords. It provides advantages in terms of protection against different attacks and offers a robust evaluation based on relevant criteria.

“…Classical cryptography methods, such as RSA [25,24,28,29,26,27], were initially developed to protect text-based information, and are not well-suited to the encryption of multimedia data [5][6][7], including images. This is due to several reasons.…”

With the growing need for secure multimedia data transmission, image encryption has become an important research area. Traditional encryption algorithms like RSA are not well-suited for this purpose, leading researchers to explore new approaches such as chaotic maps. The present study introduces a new image encryption algorithm that utilizes an improved Rossler system as a keystream generator. The improved Rossler system is an enhanced version of the original Rossler system, which has been optimized for better chaotic behavior and improved security. For the confusion part, we combine DNA encoding techniques with Baker maps to ensure high levels of security. Various performance metrics, including NPCR, UACI, correlation coefficient, histogram analysis, and key sensitivity analysis, were used to evaluate the proposed scheme. The results showed that the proposed method surpassed several existing image encryption methods in terms of both security and efficiency.
