“…A method of data cryptography is considered a good method if it satisfies the following:  Simplicity: Easy to program and implement and easy to modify.  Efficiency: Maximizing the method throughput (byte processed per second), this can be achieved by minimizing the encryption time (ET) and decryption time (DT) [31][32][33][34].…”

Secret messages which contain valuable confidential and private information require high-level protection to make the hacking process impossible. In this research paper, a new and simple method of data cryptography will be introduced. The proposed method will use two image_keys to generate the needed private keys. The private keys will be categorized into two sets: the first set will be used to form the RLDs required for the rotation right of each byte, while the second set will be used to apply XORing operations. The image_keys will be kept secret to avoid hacking them. The method will use a variable block size to divide the data, and it will use a variable number of rounds. The block size and the number of rounds are to be kept secret. The method will be implemented using various messages and various block sizes and a number of rounds, the obtained results will be compared with DES results to show how the proposed method will keep a high throughput when increasing the block size and increasing the number of rounds.

Color image may be secret or holding secret data, also secret messages may be so confidential. To protect these data, we have to use a simple and efficient method. In this research a method of data encryption-decryption will be presented. The suggested method will use a complicated PK to apply image encryption/decryption using XORing operation, the used image key will be reordered using a secret ordering sequence. Any modifications made to the PK during the decryption process will be regarded as a hacking attempt and result in corrupted decrypted data; hence, the encryption and decryption processes must employ the same secret information. The PK will provide an enormous key space that could resist any type of hacking attempts. The suggested method will be tested and the obtained results will be compared with those of DES and AES, the throughputs and speedup will be calculated. It will be shown how easily we can use encrypt decrypt color images with any size using a fix image key, and it will be shown how the suggested method maintain desirable values of MSE and PSNR parameters.

“…And due to these reasons and due to the importance of digital images, the number of people lurking in them has increased, which requires us to provide the necessary protection for them, especially if the communication environment is not safe. The protection must prevent the image from being hacked [43][44][45][46][47][48][49][50].…”

A simple, multipurpose, efficient, sensitive and highly qualities method of image cryptography will be introduced in this research paper. The method will be easily used to encrypt-decrypt any type of image with any size (gray and color images). The proposed method will secure the image by providing a high degree of image protection based on using a complex private key, which contains eight values, each of the has a double data type. The private key will provide the required key space to resist any hacking attack. The private key components will be used to calculate the size of the generated 3D chaotic logistic key. The private key will also be used to run two chaotic logistic map models to get two different chaotic keys base on the chaotic parameters values included in the private key. Two rounds of XORing operations will be used to generate the encrypted-decrypted image. The generated outputs of the proposed method will be sensitive to the selected value of the private key. The proposed method will be very flexible, changing the source image or/and changing the private key will not require any changes in the method algorithm. The proposed method will be tested and implemented using various image, the obtained results will be discussed to prove the features provided by the method: quality, sensitivity, security and efficiency.
