    Abstract
    In this study the authors use the One Time Pad Algorithm on Three Pass Protocol scheme. Algorithm One Time Pad is known as a perfect algorithm and very difficult to resolve, the encryption key is used only once for a single message so that there is no looping key usage. Three pass protocol scheme is a method in which the process of sending a message does not have to share the encryption key, so that the two sides both sender and recipient do not know each key respectively. One Time Pad in Three Pass Protocol scheme aims to make security more messages private. The process of sending a message is done by changing the position of the rotation technique ciphertext sequence, so that the resulting ciphertext is different from the transmitted ciphertext. This rotation technique aimed at improving security in the process of sending a message. The time required for the execution of the program depends on the generation of random key and the plaintext length.
     
    Pada penelitian ini penulis menggunakan Algoritma One Time Pad pada skema Three Pass Protocol. Algoritma One Time Pad dikenal sebagai algoritma yang sempurna dan sangat sulit dipecahkan, kunci enkripsi hanya digunakan satu kali untuk satu pesan sehingga tidak terdapat perulangan penggunaan kunci. Skema three pass protocol merupakan suatu metode dimana dalam proses pengiriman pesan tidak perlu berbagi kunci enkripsinya, sehingga kedua belah pihak baik pengirim dan penerima tidak saling mengetahui kunci masing-masing. One Time Pad dalam skema Three Pass Protocol bertujuan agar keamanan pesan lebih terjaga kerahasiannya. Proses pengiriman pesan dilakukan dengan teknik rotasi yaitu mengubah posisi urutan cipherteks, sehingga cipherteks yang dihasilkan berbeda dengan cipherteks yang dikirim. Teknik rotasi ini bertujuan meningkatkan keamanan pada proses pengiriman pesan. Waktu yang diperlukan untuk eksekusi program tergantung pada pembangkit random kunci dan panjang plainteks.
