    Abstract
    Technological developments force us to do something especially in terms of security, files that are very vulnerable to be known, retrieved or even manipulated by others who are not entitled. Security on video files is the right step, many video files are scattered without any security. In this study analyzed and compared the performance of Vigenère cipher algorithm and reliance cipher algorithm in video file security. Both are asymmetric type cryptographic algorithms that have private and public key pairs for encryption and decryption processes, to find out which algorithms are more accurate by observing the running time and complexity of the algorithm, conducted in 5 experiments with different file sizes, character counts and keys, with an average time difference of encryption 13482 miliseconds and decryption 11384 miliseconds. Obtained results where the vigenere cipher algorithm has a faster encryption and decryption process than the encryption process and decryption algorithm railfence cipher.
     
    Perkembangan teknologi memaksa kita untuk melakukan sesuatu hal terutama dari segi keamanan, file yang sangat rentan untuk diketahui, diambil atau bahkan dimanipulasi oleh pihak lain yang tidak berhak. Pengamanan pada file video merupakan langkah yang tepat, banyak file video yang tersebar tanpa ada pengamanan. Dalam penelitian ini menganalisis dan membandingkan kinerja algoritma vigenere cipher dan algoritma railfence cipher dalam keamanan file video. Keduanya merupakan algoritma kriptografi jenis asimetris yang memiliki pasangan kunci privat dan publik untuk proses enkripsi dan dekripsi, untuk mengetahui algoritma mana yang lebih akurat dengan mengamati running time dan kompleksitas algoritmanya, dilakukan dalam 5 kali percobaan dengan ukuran file, jumlah karakter dan kunci yang berbeda, dengan rata-rata selisih waktu enkripsi 13482 milisecond dan dekripsi 11384 milisecond. Didapatlah hasil dimana algoritma vigenere cipher mempunyai proses enkripsi dan dekripsi yang lebih cepat dibandingkan proses enkripsi dan dekripsi algoritma railfence cipher.
