Abstract
An innovative alternative method in the field of security that can enforce safety and security of information has been proposed here by performing audio encryption. Cryptography, a way to secure communications, allows only the sender and the intended recipient of a message to access its contents. Cryptography is derived from the Greek word “Kryptos,” meaning hidden, which is associated with content hiding by encryption. In this paper, we develop a novel time-stamp-based audio encryption method using the mind-cracking number place challenger Sudoku puzzle of higher dimension, i.e., 16 × 16 (popularly known as Super Sudoku) to add a new era in the field of security. In this work, we have developed a Super Sudoku cipher by applying time-stamp in it. Immediately after that, the extracted audio frames of the input audio files are XORed with our developed innovative Cipher to generate encrypted audio frames. Then these encoded audio frames are converted to an encrypted audio file to transmit with safety and security. At the receiver end, by applying the same cipher key, we can extract our original audio file.
