Trunk encryption device - this page is a stub - wanted item

BVO-T was a Trunk Encryption Device (TED), developed around 1981 by Philips Usfa in Eindhoven (Netherlands) as part of the ZODIAC integrated communications network of the Dutch Army. It allows a transfer speed up to 2 Mb/s and was used as a gateway to other NATO/USA networks. It is compatible with the American KG-81, for which the WALBURN encryption algorithm was used.

BVO is the abbreviation of Bundel Vercijfer- en Ontcijferapparaat (Trunk Encryption Device). For the ZODIAC defense network of the Dutch Army, Philips developed two versions of the BVO, both of which could run at a speed of 2Mb/s. Keys are loaded by means of a DS-102 compatible fill device, such as the KYK-13 or KOI-18.

BVO-M uses a proprietary encryption algorithm developed at Philips. It is backwards compatible with the earlier 1Mb/s Mucolex. BVO-T has the same form-factor, but is compatible with the American KG-81, allowing the integration of ZODIAC with US and NATO radio networks.
  

At present, no further information about BVO-T is available. To get a better understanding of the device, check out our page about the Philips BVO-M and the American KG-81.
