Secure data transmission through fractal-based cryptosystem: a Noor iteration approach.

The data must be protected from cyber-attacks that benefit from the weaknesses of the databases. Our traditional techniques are unstable. They are not strong enough to withstand the sophisticated and advanced criminal methods that attackers are developing and using to access confidential information. To prevent these kinds of activities, we must use encryption techniques. The most common Brute force encryption method, which can easily break encryption that is not very strong, is one of the many encryption and decryption techniques used by cyber attackers to break unsafe techniques during data transformation over a network. This paper addresses these challenges and provides a strong and effective encryption technique. Fractals are indefinite parameters and functions that can be used to enhance encryption techniques, and one of them we used in our study was to optimize the encryption technique. In this paper, we introduced a new and reliable encryption technique that utilizes the chaotic and fractal nature of Noor iteration. Our study intends to improve real-time protection against new attack vectors. The proposed approach ensures key sensitivity by generating an initial value set throughout the Noor iteration process. Initial Key values are produced by the fractal function using the Julia set and the XOR operator. Our study shows the efficiency, reliability, and potential for secure communications. The sequence encrypts the plain text, and the entire process is evaluated using analysis that includes key space, sensitivity, differential, and statistical evaluations.
