Simulation and Analysis of MAC Security Based on NS2

Based on IEEE 802.1AF, secure key agreement and management schemes are discussed, including secure key generation and distribution, identification of Live Peer Lists and Potential Live Peer Lists. Key Selection Protocol (KSP) and LAN-based Key Server (LKS) protocol are compared in this paper. To improve the security of Ethernet, a group based MAC key selection protocol (GKSP) for large Ethernet networks is provided, simulated and validated
