Encryption is the process of encoding information (in this case audio signals) in such a way that eavesdroppers or hackers cannot understand it, but authorized parties can access it. Transforming an encrypted message to its original form is accomplished by a process known as Decryption. If the number of ones are Even then use Permutation 1.

These cookies will be stored in your browser only with your consent. AES is faster than 3DES. Encryption algorithms protect the data so it cannot be read by a third-party while in transit. The algorithm offers reasonable security and achieves a prominent signal-to-noise ratio (SNR). Symmetric encryption uses the same key for encryption and decryption. Audio cryptography encryption is the method of including the noise (key) to the plain text audio and while decryption is the process of taking out the original plain text back by using the same key. At the time this paper is written, only few references available. Histogram for the original Audio signal is shown in the bellow graph. 20, no. Protection of audio from the eavesdroppers plays a critical task for the technologist.

This protocol uses one key for encryption and decryption. This form of the encryption algorithm is a symmetric key block cipher which is characterized by 128-bit block size and whose keys' size can run up to 256 bits. In the case of a streaming algorithm, the data is not retained in the system's memory; hence, one can say that this is much safer compared to the block algorithm as data is not retained in the system without encryption.
