Improve the security for voice cryptography in the RSA algorithm

Network security aims to protect network data to improve its integrity and usability. The cryptography methods used in network security aid in the transfer of data in a specified manner that can only be read and processed by the intended recipient. Furthermore, the speech is encoded as a cipher voice, which is subsequently decoded on the receiving end. The voice is also encoded as a cipher voice, which the receiver decodes. By upgrading the RSA algorithm, the proposed approach in this work improved the security of voice cryptography. The goal of our research is to use the RSA algorithm to increase the security of voice cryptography in images. The first step is to use the RSA method to generate two public keys for the voice before encrypting it in the image (sender). The second phase is decrypting each of the images.
