Several Authentication and Key Agreement (AKA) Protocol have been proposed in the past, though major security flaws have been addressed, like key-compromise impersonation attack, unknown-key sharing attack, not fulfilling the security features of AKA. Thus, this paper proposes a novel mechanism of Pairwise Disjoint Key Authentication (PDKA) to abort the reverse derivation. To examine the authentication schemes realistically, the real time multimedia server-client system are installed in the Linux Mint platforms. To inspect the aforesaid metrics, the multimedia clients are initiated of voice call connection. The examination result is shown that the proposed scheme of PDKA achieves the better results relatively than the other existing schemes. The result is evaluated using real time network analyzer tool. © IDOSI Publications, 2014.
