EXTENDED TINY ENCRYPTION ALGORITHM EQUIPPED WITH ARABIC SCRIPT (AXTEA)

Abstract

Cryptography is a science that deals with secret writing. Now a days, every programming language, browsers, and famous databases support the UTF-8 code. Therefore, it is easier to store Arabic script languages into the database. Most encryption algorithms are used to convert plain text to cipher, whereas cipher is usually in the same language with the text being ciphered or in special characters. In this paper, we enhanced an algorithm (XTEA) and converted English plain text to Arabic script language (for instance, Arabic, Urdu, and Persian) using Extended Tiny Encryption Algorithm (XTEA). The proposed algorithm was implemented in PHP, and the results show that the resultant cipher was more secure. It enhanced the security of data because the medium of the ciphered text was not same as plain text. We named our proposed algorithm as Arabic Extended Tiny Encryption Algorithm (AXTEA).
