Short Message Services (SMS) is one of the cellular phone services which provides its user to communicate via short message. SMS is very popular because of the inexpensive cost, short timing dispatch to the recipient, and could be sent to multiple recipients at a time. However, communicating via SMS isn't an end-to-end protocol, which means that the sender doesn't receive the message directly but needs to goes through a message network. In the SMS network, there are gaps that can create SMS security is threatened. In this Final Project, a program is built to improve the message confidentiality during communication. The program is built using Identity-based Cryptography (IBC) algorithm to perform an encryption process so that the message confidentiality could be improved. IBC is a public-key cryptography system that uses any string which represents one's identity as a public key. The program is built only as a simulation and the program is not implemented directly into the celular phone. The Program is developed using the Visual Studio 6.0 and in the Windows operating system. Based on testing performance, the program is capable of doing encryption and decryption process.
