Iyswarya R., Muthunagai S.U., Poorani S., Anitha R. . KDC Authentication for Secured Communication using Four-Way Handshake Protocol. International Journal of Computer Applications. 174, 30 ( Apr 2021), 8-12. DOI=10.5120/ijca2021921229
All the Wi-Fi connected devices are currently secured by WPA2 protocol but in recent studies it proves that the major vulnerability which exploits the man-in-the-middle attack it also referred as KRACK (Key Re-installation AttaCK). In this research, the improvisation of the current scheme of 4-way handshake in the WPA2 (Wi-Fi Protected Access-2) is discussed and has an advantage of already-in-use key exchanged in the handshake. The Key Distribution center (KDC) protocol improvises the WPA2 by randomly generating a session key per communication along with 4-way handshake key exchange in the protocol. Session key is used as a Pre- shared key for the derivation of further components in the key exchange. Thus, the confidentiality in the proposed protocol is maintained in secured manner.
