ABSTRACT:
A method for providing security in a computing network. A device connects to a network and authenticates itself with a server. Next, the server adds the IP address of the device to a list of trusted devices. The server broadcasts the trusted IP address to all devices in the network to which the newly authenticated device is allowed to communicate. The devices in the network add the trusted IP address to a list of trusted address stored on each device. The server may also transmit its stored list to the newly authenticated device. After a device has received a packet, it determines if the IP address associated with the packet is on its trusted list. If it is, the device processes the packet. If the IP address is not found on the safe list, the device queries the authentication server to determine if the IP address is safe.
