Implementasi Kriptografi Kunci Publik Dan Privat Dalam Mengamankan Pesan Dengan Metode Affine Cipher
Abstract
Perkembangan zaman membuat pertambahan data semaking meningkat. Dengan
peningkatan data yang begitu pesat, tingkat keamanan pada data tersebut menjadi
lebih rentan. Ada banyak pencurian data yang dilakukan oleh pihak yang tidak
bertanggung jawab. Dibutuhkan teknik pengamanan data yang dapat menghindari
penyalahgunaan pada pengiriman pesan. Kriptografi adalah salah satu teknik yang
dapat digunakan dalam melakukan pengamanan data. Algoritma Affine Cipher
dapat digunakan untuk melakukan proses enkripsi dan dekripsi pada pesan. Affine
cipher memiliki kunci yang berbeda pada saat proses enkripsi dan dekripsi. Kunci
tersebut akan dilakukan penambahan sejumah karakter. Tingkat keamanan
algoritma Affine cipher adalah sangat baik. Dengan penerapan teknik ini pada
pengiriman pesan, keamanan dari pesan tersebut dapat ditingkatkan.
Kata Kunci: dekripsi, enkripsi, kriptografi, Affine, Cipher
