ADOPSI REPETITIF COVERTEXT PADA MEODEL ENKRIPSI PDAC
Abstract
Teknik kriptografi dan steganografi berperan penting dalam pengamanan informasi. Gabungan keduanya memberikan tingkat keamanan informasi yang lebih kuat dan sulit dipecahkan. Model enkripsi Parallel Encryption with Digit Arithmetic of Covertext (PDAC) mengadopsi kriptografi dan steganografi dalam pengamanan pesan. Penggunaan PDAC sebagai algoritma enkripsi memerlukan kesesuaian pada proses pemilihan coverteksnya. Ketepatan jumlah covertext dalam PDAC mempengaruhi berjalan atau tidaknya PDAC dalam mengenkripsi pesan. Jika jumlah pesan sangat panjang maka akan menjadi sulit bagi pengguna dalam menentukan coverteksnya dan jika jumlah covertext PDAC tidak sesuai, maka proses enkripsi akan menjadi tidak sempurna. Penelitian ini melakukan pengubahan model yang bertujuan menutup celah PDAC. Modifikasi model yang diusulkan mengadopsi penggunaan covertext yang diterapkan secara berulang. Perulangan covertext yang diterapkan dalam PDAC mampu memproses pengamanan informasi secara menyeluruh. Keuntungan lain yang diperoleh ialah modifikasi ini memudahkan pengguna untuk menggunakan PDAC tanpa harus memenuhi kebutuhan minimum covertextnya
