TACLANE, for tactical local area network (LAN), is a family of bulk encryption of packet stream devices specified by the National Security Agency and manufactured by General Dynamics. The family, all intended for high-speed IEEE 802.3/Ethernet interfaces, is designated KG-175. Some models (TACLANE Classic, TACLANE E-100) are no longer in production, with the current versions either smaller than the original, or able to operate at higher speeds (e.g., Gigabit Ethernet).[1] It encrypts packets within frames, and certainly not all bits; the frame headers and trailers must be present for the LAN to work.

It is a derivative of the FASTLANE KG-75 for the earlier high-speed Asynchronous Transfer Model (ATM), Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy telecommunications technologies.

Applications

TACLANE is the main interface, for sending and receiving compartmented intelligence information, between the existing TROJAN SPIRIT service and the newer, common-user Joint Network Node and Warfighter Information Network-Tactical military communications architectures.
