摘要：A network security device is connected between a protected client and anetwork. The network security device negotiates a session key with any other protectedclient. Then, all communications between the two clients are encrypted. The inventivedevice is self-configuring and locks itself to the IP address of its client. Thus, the client
cannot change its IP address once set and therefore cannot emulate the IP address ofanother client. When a packet is transmitted from the protected host, the security devicetranslates the MAC address of the client to its own MAC address before transmitting thepacket into the network. Packets addressed to the host, contain the MAC address of thesecurity device. The security device translates its MAC address to the client's MACaddress before transmitting the packet to the client.
