KG - 175
The TACLANE (KG-175) is short for Tactical FASTLANE ® and was developed by the National Security Agency (NSA) to provide network communications security on Internet Protocol (IP) and Asynchronous Transfer Mode (ATM) networks for the individual user or for enclaves of users at the same security level. The KG-175 is a low-cost, Type 1, key-agile, in-line network encryptor for deployment in Department of Defense (DOD) tactical and strategic networks. KG-175s meet the needs of users who must communicate securely over legacy networks such as the Mobile Subscriber Equipment (MSE) packet network and Secure Internet Protocol Router Network (SIPRNET), and emerging ATM networks. KG-175s provide encryption for IP datagram traffic. ATM traffic and IP datagrams are encapsulated in ATM cells to support a variety of IP, ATM and mixed network configurations. KG-175s can be used to overlay Secure Virtual Networks on top of existing public and/or private network infrastructures.

Key management includes automatic key generation via public key cryptography. TACLANE not only employs access control, but includes compromise recovery that is suitable for tactical as well as fixed network environments. It uses a cryptographic ignition key (CIK) that renders the device unusable and UNCLASSIFIED when it is removed.
