Abstract

Perkembangan teknologi saat ini sudah sangat pesat. Dengan perkembangan teknologi saat ini semua data dan informasi bisa secara cepat dimiliki oleh manusia. Semakin berkembangnya teknologi semakin meningkat juga kejahatan terhadap keamanan pesan yang dikirim. Oleh karena itu sangatlah dibutuhkan suatu proses penyandian/enkripsi pada pesan teks. Pada penelitian ini menggunakan teknik kriptografidengan Algoritma RSA. Algoritma RSA merupakan Algoritma asimetris yang dimana memiliki dua kunci yaitu public dan private. Alogritma RSA memiliki tingkat kesulitan mencari kunci dekripsi. Yang dimana dengan cara memfaktorkan suatu bilangan bulat menjadi faktor-faktor prima. Kemudian peneliti juga menggunakan teknik steganografi yaitu LSB (Least Significant Bit). Steganografi LSB disini sebagai media penyimpanan pesan teks pada citra. Tujuan menggabungkan algoritma RSA dan LSB (Least Significant Bit) adalah untuk meningkatkan pengamanan pesan teks dengan cara menyandikan sebuah pesan tersebut.
