Abstract

Cryptography is the art of destroying secret data making it unintelligible and illegible, in this paper research a method based on the use of digital images will be introduces. The method will use a digital color image to extract all necessary working and sup keys. The method will be implemented to show how it increases the cryptography process efficiency. The proposed method will be compared with other popular method such as DES, AES, and LED methods, it will be shown how the introduced method will decrease both the encryption and decryption times eliminating some important tasks in cryptography process like key generation and key scheduling.
