Nowadays cryptography plays a major role in information security because encryption and decryption is very hard to crack. Data encryption and decryption fulfill these demands. Many researchers have proposed many encryption and decryption algorithms such as AES, DES, RSA, and others. But most of the proposed algorithms encountered some problems such as lack of robustness and significant amount of time added to packet delay to maintain the security on the communication channel between the terminals. In this paper, we enhance the security goals via encrypting and decrypting phone numbers by using a set of packs which maintains the security on the communication channels. In encryption we assign numbers for the set of packs and we convert the decimal to hexadecimal to encrypt the data and to decrypt vice versa. © 2015, International Journal of Pharmacy and Technology.
