Pengembangan Aplikasi Pertukaran SMS Rahasia Berbasis Android Menggunakan Algoritme RSA

Abstract

Delivering message using short message service (SMS) is very familiar among the users of cellular phone in Indonesia. SMS center (SMSC) is required to keep and deliver SMS from one device to another device. The weakness of SMS technology of is that the encryption only works between mobile station (MS) and base transceiver station (BTS). Meanwhile on the other side, it is fully opened without encryption so that some attacks such as hacking and modification become highly possible. This research utilized RSA algorithm to secure the delivery of SMS between one device and another. The advantage of RSA method is that it does not need to exchange secret key and it is able to keep the original content of SMS. It was found that RSA applications can be applied in order to guarantee the security of SMS contents.
