Abstract

Penerapan kriptografi pada asset budaya sangat perlu dilakukan, karena banyaknya klaim budaya Indonesia oleh negara asing. Oleh karena itu penelitian ini menggunakan tembang macapat Sinom, Pangkur, Pocung, Kinanti. Pada penelitian ini membandingkan algoritma Caesar Cipher dan Rail Fence Cipher untuk mengetahui proses penyandian dan efektifitas waktu enkripsi dan deskripsi. Waktu proses menunjukkan waktu deskripsi lebih lama dibandingkan enkripsi. Waktu rata-rata enkripsi algoritma Rail Fence Cipher lebih cepat yaitu adalah 0.000254 detik dibandingkan dengan Caesar. Waktu rata-rata enkripsi Rail Fence Cipher adalah 0.000254 detik dan waktu deskripsi adalah 0.000475 detik. Waktu enkripsi terpendek Pocung dan Kinanti. Rail Fence lebih aman dibanding Caesar Cipher.

Abstract

Security and confidentiality in communicating become a necessity so that the information sent and received is not misused by irresponsible parties. Cryptography not only provides a tool for information security but is also a useful technique for the security and confidentiality of information. This study aims to implement the Caesar Cipher and Rail Fence Cipher algorithms to determine the encoding process and also to determine the effectiveness of the encryption time and description of the two cryptographic techniques. The processing time of the two methods shows that the description time is longer than the encryption process. The average execution time of the Caesar Cipher algorithm is faster than the Rail Fence Cipher. The average encryption time is 0.0000802 second and the description time is 0.000131 second, however Rail Fence is more secure because the text process is sent in a zig zag form, so the received ciphertext is more secure than Caesar Cipher. Caesar Cipher is faster because the letter encoding process is shifted as many keys as desired. Keywords: Caesar Cipher, Rail Fence Cipher, Key, ziq zaq, Plaintext, Chipertext
