ATM CATAPAN® is a high-grade crypto capable of protecting material up to TOP SECRET Codeword which has been designed for use on either a public or private ATM network.
The ATM crypto project began in December 1993 when ATM was emerging as one of the leading WAN protocols being offered by Telecommunications providers
CATAPAN® is a CESG design, but a development contract was let with TRL in August 1996
DAC (Design Accreditation Certification) was achieved in 2003 and CATAPAN® is now in production
CATAPAN® is a Network Crypto ~ NOT A LINK CRYPTO (although it can be used as a link crypto if only two devices are involved)
The network aspect brings many advantages the main being that you do not need a pair of cryptos on every leased line as is the traditional way of providing secure network services. Instead just a single device at every site radically reducing the number of cryptos required
