Abstract
Due to the huge developments in mobile and smartphone tech nologies in recent years, more attention is given to voice data transmission such
as VoIP (Voice over IP) technologies, e.g., (WhatsApp, Skype, and Face Book
Messenger). When using VoIP services over smartphones, there are always
security and privacy concerns like the eavesdropping of calls between the
communicating parties. Therefore, there is a pressing need to address these risks
by enhancing the security level and encryption methods. In this work, we
suggest a new scheme to encrypt VoIP channels using (128, 192 & 256-bit)
enhanced encryption based on the Advanced Encryption Standard (AES) algo rithm, by extending it with the well-known Diffie-Hellman (DH) key exchange
method. We have performed a series of real tests on the enhanced (AES/DH)
algorithm and compared its performance with the generic AES algorithm. The
results have shown that we can get a significant increase in the encryption
strength at a very small overhead between 4% and 7% of execution time.
