Abstract: Scrambling is widely used to protect the security of data files such as text, image, video or audio files; however, it is not the most efficient method to protect the security of the data files. This article uses NTRU public key cryptosystem to increase the robustness of scrambling of sound files. In this work, we convert the sound file into text, and then scramble it in the following way: first, we encrypt the header of the sound file then, scramble the data of the file after the header in three stages. In each stage we scramble the data of the sound file and keep the original order of data in an array then, the three arrays are encrypted by the sender and sent with the encrypted header to the receiver in one file, while the scrambled data of the sound file is sent to the receiver in another file. We have tested the proposed method on several sound files; the results show that the time of encryption and decryption is reduced to approximately one-third, or less, compared to encrypting the file using NTRU.
