Improving data standard methods of cryptography

Abstract

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.
