Encryption algorithms based on chaos theory are frequently used due to the sensitivity of initial conditions, control parameters, and pseudo-randomness. They are very useful for data encryption for images, audio, or videos. In this paper, a novel audio encryption method is proposed to provide information security. Firstly, the one-dimensional uncompressed 16-bit audio file of even length is taken. Then chaotic Henon map and tent map is XORed to create the pseudo-random number sequence as the secret key. Next, the secret key is XORed with the original audio file to produce a cipher audio file. The encrypted audio file can be used for the e-learning process to create an audio password that can be used as login credentials instead of an invitation link. Security analysis shows that our encryption method is better than other existing methods in many aspects with less time.
