Assalamualaikum, di pertemuan kali ini saya akan menjawab tugas dari dosen mengenai kriptografi klasik.
Berikut soalnya :
1. CAESAR CIPHER 1, berdasarkan penjelasan contoh dari cara kerja Algoritma Kriptografi Klasik CAESAR CIPHER 1, sebagai berikut:
a.
lakukan transformasi +5
b.
pesan yang ditransformasi “KEAMANAN SISTEM”
Sedikit mengenai Caesar Cipher 1, jadi Caesar Cipher adalah algoritma yang dimana cara bekerja nya tiap huruf alfabet = n + pesan
Ketentuan Pengerjaan : Pesan "KEAMANAN SISTEM" dan transformasi +5
