Abstract: <br /> <br /> <br /> <br /> <br /> <br /> Messaging technology in mobile telecommunication services has evolved from just a simple text-based messaging service to message that can contains graphics, voices or <br /> <br /> <br /> <br /> <br /> <br /> videos. This technology, Multimedia Messaging Service (MMS), currently is a standard service given by cellular operators. However various security threats can occur such as theft so that thief can read all the messages in cellphone, messagetapping, et cetera. <br /> <br /> <br /> <br /> <br /> <br /> In this final project, a software is developed to secure MMS messages using symmetric and asymmetric-key cryptography. It uses Rivest, Shamir and Adleman <br /> <br /> <br /> <br /> <br /> <br /> (RSA) algorithm for asymmetric-key and Advanced Encryption Standard (AES) algorithm for symmetric-key. The software is implemented by building main software <br /> <br /> <br /> <br /> <br /> <br /> in two entities, a software installed in cell phones and a web-based software. Main software functions are securing MMS using encryption, generating digital signature. <br /> <br /> <br /> <br /> <br /> <br /> Meanwhile, web-based application is for transferring public key among users which can be accessed through main software. Main software was developed for cellular <br /> <br /> <br /> <br /> <br /> <br /> telephone using Symbian operating system version 70 or 80 series 60 and Software Development Kit (SDK) from Nokia also Microsoft Visual Studio .NET123 2003 with C++ programming language. According to the test, the software is able to process encryption, decryption, digital signature signing and verification at MMS, but <br /> <br /> <br /> <br /> <br /> <br /> is not able to send encrypted MMS so it is open to further development. At the end of this final project, it can be concluded that symmetric and asymmetric-key <br /> <br /> <br /> <br /> <br /> <br /> cryptography is one of the suitable solution and can be applied for securing MMS in cell phones.
