Abstract – Information security involves safeguarding sensitive data and IT networks from unauthorized access and cyber-attacks. To address this need, various techniques and algorithms have been introduced. In this context, we propose a new technique aimed at protecting information from diverse threats, enhancing user confidentiality, and ensuring high data integrity and availability.

In this paper, we introduce a method for generating cipher text by performing multiple rounds of operations. In the first round, we convert the plaintext into ASCII code, then into hexadecimal, and subsequently reverse the code. These transformed values are then stored in blocks, where various operations are performed to generate the cipher text.
