KRIPTOGRAFI AES MODE CBC PADA CITRA DIGITAL BERBASIS ANDROID

Authors

Abstract

Keamanan merupakan salah satu aspek penting dalam pengiriman data maupun komunikasi melalui jaringan, citra digital merupakan salah satu data yang mengandung banyak informasi, oleh karena itu untuk menjaga keamanan dan kerahasiaan suatu data maupun informasi salah satunya dengan menggunakan teknik kriptografi. Kriptografi adalah suatu ilmu dan seni untuk menjaga keamanan data atau pesan. Salah satu algoritma yang sering di gunakan saat ini adalah AES (Advanced Encryption Standard). Penerapan kriptografi pada penelitian ini menggunakan AES dengan panjang kunci 128 bit yang beroperasi pada mode operasi blok CBC(Cipher Block Chaining) dan aturan padding PKCS#7 (Public – Key Cryptography Standards) agar dapat menjaga ukuran masukan plainteks tetap berada ukuran bloknya. Android merupakan operasi sistem mobile terbaru dari google yang sedang populer saat ini, karena itu banyak serangan menargetkan smartphone berbasis Android. Penelitian ini bertujuan untuk membuat suatu perangkat lunak pada smartphone android menggunakan algoritma kriptografi AES yang bertujuan untuk mengamankan data citra digital dengan mengubah isi element penyusun pada tiap piksel agar informasi yang terkandung tidak diketahui oleh orang lain. Hasil dari penelitian yaitu menghasilkan sebuah perangkat lunak pada smartphone berbasis android yang dapat digunakan untuk mengamankan informasi citra digital dan mengembalikan informasi citra digital yang teracak menjadi informasi yang dapat dikenali.
