Abstract

Teknologi saat ini berkembang sangat pesat dan berpengaruh pada keseharian kita dalam berkomunikasi, dampak perkembangan teknologi saat ini, mengirim dan menerima pesan dapat dilakukan dengan mudah dan cepat. Selain itu, perkembangan teknologi juga berdampak pada berkembangnya penyadapan pesan illegal yang dilakukan oleh pihak yang tidak seharusnya mendapatkan pesan. Salah satu solusi untuk masalah tersebut adalah kriptografi dan steganografi . Kriptografi sendiri adalah ilmu menyandikan pesan, sedangkan steganografi adalah ilmu menyembunyikan pesan ke dalam media lain. Pada tugas akhir ini menerapkan pengamanan pesan menggunakan kombinasi kriptografi dan steganografi audio. Proses diawali dengan menyandikan pesan dengan algoritma yang diciptakan oleh Rivest, Shamir, dan Adleman (RSA), pesan yang sudah disandikan akan disembunyikan ke dalam audio dengan Transformasi Wavelet Diskrit. Hasil uji coba menunjukkan bahwa pesan dapat diamankan dengan baik. Pada uji coba dengan sampel audio file WAV berdurasi 17 detik disisipi 50.107 karakter pesan, hanya 8,7% responden yang berpendapat bahwa audio asli dan audio yang sudah disisipi pesan rahasia keduanya berbeda.

Technology is currently developing very rapidly and affects our daily communication, the impact of current technological developments, sending and receiving messages can be done easily and quickly. In addition, technological developments also have an impact on the development of illegal message intercepts carried out by people who are not supposed to receive messages. One solution to this problem is cryptography and steganography. Cryptography itself is encoding messages, while steganography is hiding messages into other media. In this final project, we apply message security using a combination of cryptography and audio steganography. The process begins by encoding the message with the Rivest, Shamir, dan Adleman (RSA) algorithm, the message that has been encoded will be hidden into the audio with Discrete Wavelet Transform (DWT). The test results show that messages can be well secured. In a trial with a sample of a 17-second WAV audio file with 50,107 message characters inserted, only 8.7% of respondents thought that the original audio and the audio that had been inserted with a secret message were different.
