Historically developed to ensure secrecy in the mail, encryption of information today is used more broadly to prohibit access to or modification of sensitive data and ensure confidentiality in computer applications, so cryptology is the science that studies the scientific aspects of these techniques (cryptography and cryptanalysis) and it is essentially based on arithmetic [1]. Encryption techniques have evolved since their inception: modern encryption uses the power of modern computers. Since the d
