Implementation of Internet protocol security in video conferencing over IPV4/V6 on the Linux platform

This paper outlines the architectural principles of secured video conferencing using Internet protocol security (IPSec) over IPv4 and IPv6. In the non-secured video conferencing, an attacker can sniffed, eavesdropped unauthorized interception and spoofed the packet sender/receiver address. A secured video conferencing test-bed consisting two PCs with IPv4/IPv6 stack has been implemented on the Linux platform using IPSec protocol. The security test includes FTP and PING/PING6 between two PCs. The result shows that the sniffer cannot sniff the packets transfer between two PCs.
