English Abstract

Lately, the development and progress have become significant in the field of information technology, especially in the field of data transmission via internet.

One kind of the data transfer is voice.

In addition to that, the development in the field of mobile devices, which is possibility supplying the device by internet service became a paradigm shift, that grabs people in hugely way to be used widely.

These developments in the field of technology are concurring many problems, where it had a direct impact on this development and the turnout by the users.

Some of these problems: eavesdropping call between the two parties, they must choose secured way to transfer audio to the other party.

As well as when untrusted users enter the program which supports audio transfer, the administrators can deal with this problem by identifying a list of authorized users to enter this program.

In this thesis, the model’s implementation has done on a mobile device (Which is operating by (Android) system).Because recently it has been widely used among different people, dealing with sound transfer process has been via the internet using the SIP server to authenticate the communication process between two parties, and to make sure the reliability of persons and this process, after that RSA algorithm (key size used 1024 bit) is using of increased the encryption keys strength and exchanged between the two parties and to ensure that the packet transmitted every time.

(AES) algorithm used to encrypt the package, the reason of choosing this algorithm that is very effective, which is associated with the encryption speed.

Key size used in the proposed model with AES is (256 bit) to ensure the secured and speed of the proposed operation.

Results of experiments showed that the sent 20016 byte to each sender packet size, which is including 16 byte for key.

It will be receiving 20000 bytes, and the total time between the encryption and decryption process for each packet is 2-5millisecond.

These results depend on the quality of service (Internet) from one side and by the number of users from the other side where the commensurate is affecting of extrusive.
