Abstract
Dunia digital memiliki peran penting dalam kehidupan sehari-hari khususnya dalam pertukaran informasi seperti file video, namun pertukaran informasi di jaringan internet memiliki keamanan yang berisiko. Kriptografi merupakan salah satu solusi untuk mengamankan file video sehingga informasi file tersebut tersamarkan. Penelitian ini akan mengimplementasikan dan mengkonstruksi program aplikasi kriptografi video menggunakan transposisi dan Random Matrix Affine Cipher untuk mengamankan file video serta menganalisis peningkatan keamanan dari algoritma Affine Cipher asli menjadi algoritma Random Matrix Affine Cipher. Kriptografi video merupakan penggabungan dari kriptografi pada gambar dan kriptografi pada audio. Pada file video, dilakukan proses pemisahan kumpulan frame (gambar) dan data audio. Kemudian, urutan frame ditransposisikan menggunakan algoritma Affine Cipher dan nilai pixel pada setiap frame dienkripsi menggunakan algoritma Random Matrix Affine Cipher yang dapat memberikan noise yang lebih baik pada tampilan video dibandingkan algoritma Affine Cipher asli. Pada data audio, urutan dan nilai data audio dienkripsi menggunakan algoritma Affine Cipher. Kumpulan cipher frame dan cipher audio kemudian digabungkan kembali sehingga menghasilkan cipher video (video yang tersamarkan). File cipher video kemudian dapat didekripsi sehingga kembali menjadi file video asli. The digital world has an important role in everyday life, especially in exchanging information such as video files, but exchanging information on the internet has risky security. Cryptography is a solution for securing video files so that the file information is disguised. This research will implement and construct a video cryptography application program using transposition and Random Matrix Affine Cipher to secure video files and analyze security enhancements from the original Affine Cipher algorithm to the Random Matrix Affine Cipher algorithm. Video cryptography is a combination of cryptography on images and cryptography on audio. In video files, the process of separating a collection of frames (images) and audio data is carried out. Then, the sequence of frames is transposed using the Affine Cipher algorithm and the pixel values in each frame are encrypted using the Random Matrix Affine Cipher algorithm which can provide better noise on the video display than the original Affine Cipher algorithm. In audio data, the audio data sequence and values are encrypted using the Affine Cipher algorithm. The collection of cipher frames and audio ciphers is then combined again to produce a video cipher (obscure video). The video cipher file can then be decrypted so that it returns to the original video file.
