WIRELESS LINK COMMUNICATIONS BETWEEN COMPUTER AND RECEIVING NETWORK EACH RUNNING VPN SECURITY SOFTWARE AND WIRELESS-LINK SECURITY SOFTWARE

摘要

Computer communications with security marked information use a wireless link between a receiving network (RN) and a computer (WLT 1 ) each running VPN wire-link security software and wireless-link security software. A physical LAN in the network (RN) is subdivided into logical management and communications LANs. The management LAN manages a switch (L3S), access point (AP), RADIUS server (RS) and Certificate server (CS). The access point (AP) is managed only by management LAN items. The switch (L3S) ensures message traffic from management LAN ports goes only to other such ports; it and the access point (AP) are managed only by the RADIUS server via SSH. The access point (AP) contacts the RADIUS server (RS) to authenticate user certificates and receives SSH traffic only. The management LAN is synchronized to an NTP server. The communications LAN allows an authenticated computer (WLT 1 ) to communicate with a classified WAN (N 1 ). Message traffic does not go to the RADIUS server (RS) or Certificate server (CS).
