Enigma
GSM crypto-phone: ISDN connection
Enigma To effect the same secured communication with
the office and important co-workers on the public phone network,
the LineCrypt from Deutsche Telekom T-Systems/T-TeleSec, was developed,
which utilizes the same extremely secure encryption procedure
as the Enigma mobile phone, offering full protection in public
phone networks.
Similar to phone calls between two Enigma mobile phones, all
functions are controlled automatically by the built-in Net-Key
card and the key pair saved on it. Simply link the LineCrypt I+
between the existing ISDN devices, such as phone, fax or PC, and
the ISDN plug ("Plug'n'Play"). From that point on, all
conversations with an Enigma mobile phone or another LineCrypt
I+ will be secure from evesdroppers. Utilizing LineCrypt devices
in a telephone system switchboard is possible, but will require
an individual solution in order to ascertain full protection.
Special solutions could be devised and offered in cooperation
with the Deutsche Telekom partner, T-Systems/T-TeleSec.
