ABSTRAK

SMS atau Short Message Service merupakan suatu layanan pengiriman pesan singkat melalui telepon genggam. Walaupun merupakan bagian dari kemampuan standard GSM fase pertama SMS masih merupakan layanan yang banyak digunakan oleh masyarakat. Secara umum SMS tidak menjamin kerahasiaan dan keutuhan pesan yang dikirimkan oleh pengguna. Oleh karena pesan-pesan teks yang dikirim pengguna terkadang merupakan pesan yang rahasia dan pribadi sehingga kerahasiaan pesan menjadi sangat penting untuk dijaga dari orang-orang yang tidak berhak mendapatkannya. Sehingga dibutuhkan suatu sistem keamanan dalam menyampaikan pesan tersebut. Aplikasi enkripsi dan dekripsi pesan dapat meningkatkan tingkat keamanan pada layanan yang memerlukan kerahasiaan pesan. Hal ini dapat mengurangi bocornya informasi kepada pihak-pihak yang tidak berkepentingan seperti operator telepon seluler. Untuk meningkatkan keamanan dalam aplikasi enkripsi dan dekripsi pesan SMS perlu digunakan algoritma yang handal. ECC Elliptic Curve Cryptography merupakan suatu metode enkripsi alternatif yang dapat digunakan untuk menjaga kerahasiaan layanan SMS. Metode ini memungkinkan terjadinya enkripsi pesan dari telepon seluler pengirim ke telepon seluler penerima yang dituju. Dengan memanfaatkan metode ini layanan SMS dapat menjadi lebih aman karena algoritma enkripsi yang digunakan cukup tangguh dan kunci yang dipakai sukar dipecahkan. Algoritma ini merupakan algoritma kunci publik akan lebih aman jika dibandingkan dengan algoritma kunci private. Pada Aplikasi ini sistem menggabungkan antara ECC dengan algoritma kunci private supaya mendapatkan hasil yang lebih maksimal. Selain itu pada aplikasi ini juga dilengkapi dengan kompresi untuk mengurangi pembengkakan jumlah karakter hasil enkripsi. Metode Kompresi yang digunakan adalah metode Huffman.


ABSTRACT

SMS or Short Message Service is a short messaging service via mobile phone. Although it is part of the first phase of the GSM standard capabilities SMS is still a service that is widely used by many people. Generally SMS does not guarantee the confidentiality and integrity of messages that sent by the user. Therefore the text messages that sent by the user is the confidential and private message so confidentiality message is very important to be taken care from people who are not eligible. And so we need a security system in conveying the message. Message encryption and decryption application can increase the security level of the service that requires confidentiality of messages. This can reduce the leakage of information to the parties that not concerned like mobile phone service operator. To enhance security in encryption and decryption application SMS messages it is necessary to use a reliable algorithm. ECC Elliptic Curve Cryptography is an alternative encryption method that can be used to maintain the confidentiality of SMS services. This method allows the encryption of the message from senders mobile phone to recipient mobile phone. By utilizing this method the SMS service can be more secure because the encryption algorithms used are strong enough and the key that is used is difficult to solve. This algorithm is a public key algorithm will be safer when compared with the private key algorithm. In this application the system combines the ECC algorithm with private key algorithm in order to obtain maximum results. This application is also equipped with a compression to reduce swelling number of characters from encryption. Compression method used is the Huffman method.
