TACLANE

From Wikipedia, the free encyclopedia

A TACLANE (short for "Tactical FASTLANE" or Tactical Local Area Network Encryption) is a network encryption device 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. A TACLANE is a low-cost, Type 1, key-agile, in-line network encryptor for deployment in Department of Defense (DOD) tactical and strategic networks. TACLANEs allow users to communicate securely over legacy networks such as the Mobile Subscriber Equipment (MSE) packet network, Unclassified but Sensitive Internet Protocol Router Network (NIPRNet), Secret Internet Protocol Router Network (SIPRNet), and emerging ATM networks. TACLANEs 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. TACLANEs can be used to overlay Secure Virtual Networks on top of existing public and/or private network infrastructures.
