Abstract:
1. A hardware bridge for performing a bridging to perform an encryption communication between a server and a client via a LAN (local area network), the hardware bridge comprising: two channels, one of the channels making a LAN connection to either the server or the client and an other channel making a LAN connection to an internet; and a processor configured to perform a LAN packet scramble, an encryption key management and a bridging system authentication for a packet from either the sever or the client through a key exchange software mechanism, an encryption software mechanism, and an authentication information addition, wherein the hardware bridge is configured to perform a composite authentication management software mechanism provided with a plurality of authentication purpose interfaces configured to perform a composite authentication, wherein the hardware bridge is configured to perform: the composite authentication management software mechanism; and a concealment/save software mechanism; the composite authentication management software mechanism being provided with a procedure to perform a mutual authentication including an On/Off state of the concealment/save software mechanism with an opposing hardware bridge, to perform an automatic key management, and to determine a common key, and wherein the concealment/save software mechanism comprises: a key management process for managing and holding the common key even after the encryption communication when the concealment/save software mechanism is in an On state and for allowing decryption with the common key only on a sending side and preventing decryption with the common key on a receiving side; and a non-decryption file management process for managing and holding a file information encrypting and for transmitting a payload of an application communicated with the common key at an internal of a sending side hardware bridge.
