Background: Due to the internet's recent rapid expansion, security has become a crucial issue when transmitting digital data via unsecure channels. This can be applied by employing dependable encryption methods. This research brought forward a text encryption system order to create safe databases. Materials and Methods: The research uses a chaotic map based on a logistic map Due to its widespread application in scientific research. Several processes are used to carry out the encryption activity. Firstly, the text is formatted in 2D matrix of numbers converted into vector. Secondly, to create a sequence for using it in the encryption process, the chaotic system is employed. Thirdly, sorting the generated vector in order to scramble the text values based on it. The final step involves encoding the scrambled text using a mathematical operation. Also, there are many steps used in the decryption process. In the first step, the same mathematical technique is used to decrypt the encrypted text after the identical chaotic sequence has been generated. In the second step, the scrambled values are descrambled to obtain the decrypted text. Results: The experimental results demonstrate that the suggested approach obtain an excellent value of entropy equal to (0.9955) and Correlation coefficient equal to (-0.0024) and Avalanche effect equal to (0.5120) as well as the proposed system examined under NIST tests and obtain a good results (>0.01) and examined for multiple other files and obtain a good results, in terms of execution time tests, the proposed system applied in a short amount of time. Conclusion: The proposed system matched the criteria for encryption techniques in terms of high sensitivity for initial values, high security, high randomizing Whatever text is to be encrypted. Also the proposed system can be applied for real time application due to its Short implementation time.

“…It is done by converting the original plain text message into cipher text using one of the encryption algorithms [17]. There are several types of encryption methods, mainly divided into symmetric essential encryption methods, where the same key is used for encryption and decryption, and the other type is called asymmetric encryption, in which different keys are used for encryption and decryption [18]. Xor was used as a method of encryption in order to increase the level of security and increase confidentiality.…”

In the digital world, one of the crucial issues is protecting information transmitted over a public network; therefore, encryption and steganography methods must be used to raise the level of data security. This paper invests scrambling and encryption techniques to protect data and compress it to reduce its size, thus increasing system performance. The system is built on protecting gray images after passing a set of steps. The first step denotes the scrambling stage that scatters the locations of gray images by adopting a logistic map method to make it difficult for intruders. The second step contains scattering the image again using the same method but with a different equation and then performing encryption based on the xor operation. The third step represents embedding the data and includes dividing the RGB cover image into three bands where each band is divided into (4×4) blocks, and the bits are stored in the location (2,2) from each band. It tested the system's efficiency by conducting experiments on a set of grayscale images and then using PSNR as a measurement function, where the result was 67.9705.

“…Many encryption techniques were developed in the past decades to be adopted as a national standard for secure communication, like: DES, RSA, 3-DES, Two-fish, IDEA, AES. Yet, they are not suitable options for real-time multimedia cryptosystem of large size [4][5][6] . On the other hand, cryptanalysts are trying to develop their expertise and capabilities to find shortcuts to break the security of these cryptosystems.…”

“…Therefore, there is a need to develop a fast and strong cryptographic cryptosystems with pseudo-random behavior. Dynamic systems theory and chaos demonstrated promising area within the field of cryptography for research and applications [5][6][7] . Chaos-based schemes are dominant techniques due to high randomization, simple cryptographic processes, and its sensitivity to initial control parameters, such that a minor deviation in its input parameters can lead to a large change in the output range values.…”

The advancements in Information and Communication Technology (ICT), within the previous decades, has significantly changed people's transmit or store their information over the Internet or networks. So, one of the main challenges is to keep these information safe against attacks. Many researchers and institutions realized the importance and benefits of cryptography in achieving the efficiency and effectiveness of various aspects of secure communication.This work adopts a novel technique for secure data cryptosystem based on chaos theory. The proposed algorithm generate 2-Dimensional key matrix having the same dimensions of the original image that includes random numbers obtained from the 1-Dimensional logistic chaotic map for given control parameters, which is then processed by converting the fractional parts of them through a function into a set of non-repeating numbers that leads to a vast number of unpredicted probabilities (the factorial of rows times columns). Double layers of rows and columns permutation are made to the values of numbers for a specified number of stages. Then, XOR is performed between the key matrix and the original image, which represent an active resolve for data encryption for any type of files (text, image, audio, video, … etc). The results proved that the proposed encryption technique is very promising when tested on more than 500 image samples according to security measurements where the histograms of cipher images are very flatten compared with that for original images, while the averages of Mean Square Error is very high (10115.4) and Peak Signal to Noise Ratio is very low (8.17), besides Correlation near zero and Entropy close to 8 (7.9975).
