Abstract
Mp3 is one form of audio file extension that is widely used today. With a variety of uses in a variety of mp3 systems become one of the audio extensions that are commonly found in technology systems of the Internet of Things era. However, with the many uses of the .mp3 file extension, there is a new problem, namely the security of the data itself. From these problems, the author aims to examine the security of the mp3 file by designing cryptographic science-based applications. The cryptographic algorithm used in the application is a combination of the asymmetric RSA 2048 algorithm and symmetric columnic transpositions. RSA 2048 algorithm was chosen because it has a key length in accordance with NIST standards in securing data. By combining the two algorithms, the application system will have the ability to manage mp3 files and encrypt mp3 files with the results of data that cannot be played like mp3 files in general. This application system will be developed by prototype method which is the best method in developing a system with trial and error in algorithm development.

Summary
Pada perkembangan teknologi saat ini yang memasuki era Internet of Things, perangkat – perangkat yang digunakan saat ini memiliki pengembangan yang cukup signifikan daripada perangkat sebelumnya. Algoritma modern seperti RSA Jawahir, Encryption 2015 menjadi salah satu algoritma modern yang paling banyak Haviluddi Using digunakan dalam pengamanan data pada berbagai n [8] macam sistem saat ini [3]. Pada penelitian ini membuktikan bahwa kebutuhan untuk ukuran key yang lebih panjang dan kecepatan keamanan dari suatu algoritma yang menjadikan public key menjadi yang terbaik dalam manajemen dari key tersebut. Pada penelitian ini algoritma RSA – 2048 bit menjadi algoritma utama dalam pengembangan algoritma kombinasi yang akan diimplementasikan dalam sistem pengamanan data audio berbasis python. Usulan Metode enkripsi dan dekripsi dalam algoritma RSA, diperlukan perhitungan public key (e) dan private key (d), Euler tottient function φ (n) dimodelkan beberapa persamaan seperti berikut (Yousif, 2018): Pada analisis algoritma kombinasi dilakukan penelitian tentang penggabungan algoritma yang akan diimplementasikan di sistem enkripsi dan dekripsi audio.
