SMS encryption using Diife-Hellman May 4‚ 2012 Introduction 1.1 Background Nowadays mobile phone communications (phone calls) are used mostly by everyone due to the GSM technology. In mobile phones there are several services a person can use to communicate other than making a phone call such as; SMS‚ MMS‚ contact registry and cameras. The most commonly used service after phone calls is the SMS that most of us find it easier even faster to share or to communicate with one another. An SMS

2 INTRODUCTION TO CRYPTOGRAPHY 2.1 WHAT IS CRYPTOGRAPHY? The word cryptography comes from the Greek words κρυπτο (hidden or secret) and γραφη (writing). Oddly enough‚ cryptography is the art of secret writing. More generally‚ people think of cryptography as the art of mangling information into apparent unintelligibility in a manner allowing a secret method of unmangling. The basic service provided by cryptography is the ability to send information between participants in a way that prevents

code. In order to read an encrypted file‚ the receiver of the file must obtain a secret key that will enable him to decrypt the file. A deeper look into cryptography‚ cryptanalysis‚ and the Data Encryption Standard (DES) will provide a better understanding of data encryption. Cryptographic Methods There are two standard methods of cryptography‚ asymmetric encryption and symmetric encryption. Data that is in its original form (unscrambled) is called plaintext. Once the data is scrambled and in
