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.

由于初始条件、控制参数和伪随机性的敏感性，经常使用基于混沌理论的加密算法。它们对于图像、音频或视频的数据加密非常有用。在本文中，提出了一种新的音频加密方法来提供信息安全。首先，取偶数长度的一维未压缩的16位音频文件。然后将混沌 Henon 映射和帐篷映射进行异或以创建伪随机数序列作为密钥。接下来，将密钥与原始音频文件进行异或以生成加密音频文件。加密的音频文件可用于电子学习过程以创建音频密码，该密码可用作登录凭据而不是邀请链接。
