The Black•Door protects the confidentiality and integrity of Intranet and Internet Ethernet networks with the strongest commercially available cryptography. The Black•Door Ethernet Encryptor, which supports Point to Point and Multipoint information assurance configurations with unique dynamic keys, is specifically designed for real time wireline backbones and the full spectrum of outdoor Wireless WAN technologies including: Free Space Optics, licensed and unlicensed Radios.
The Black•Door transparently AES encrypts Ethernet networks. Ethernet Voice, Video or Data packets, that are destined for a device located on a remote network or a different local network segment, are AES encrypted at the Link, Network or Transport Layer and then tunneled, bridged or routed to the destination network. At the destination network the packets are decrypted and the original Ethernet packets are securely delivered to the destination Ethernet device.
The Black•Door has three core modes of operation:
The internal LAN segment transparently monitors all the packet traffic. Non Local Packets are encrypted above the Mac layer and bridged to the destination network.
Remotely destined packets are encrypted above the Network layer and then dynamically or statically routed to the destination network.
Interconnects Ethernet LANs through an IP Transparent Encrypted Tunnel. Orignal packets are entirely encrypted and then encapsulated into an IP packet that is forwarded to the destination network.
