Abstract
In our life today and with the upraise of the mobile computation and mobile phones we are using more voice applications. The voice application could then send voice information with different information over different communication channels, with an increasing need to protect this information without any delay when applying any modification on it. To protect this voice information, we encrypt it. In this paper, we are proposing a Framework using the totally reconstructed Discrete Wavelet Transformation (DWT) to encrypt the voice information in real time, where the sample rate of the encrypted voice signal is equal to the original voice signal sample rate. The framework is designed and tested with sample tests to measure the performance of this Framework, showing the speed and complexity of this Framework.
