While looking through my weekly snail after getting home last night, I opened up a advertising card deck put together by Info Security News. One particular advertisement got my attention, which I am going to send for more technical information and perhaps a catalogue. (I have used Racal-Datacom routing, bridging and mux equipment extensively, and all-in-all, they're pretty solid boxes. Caveat: This point, however, has no reflection on the quality of their s-boxes.) Here is the complete text on the postcard: "Encryption You Can Depend On! Racal-Datacom, a world leader in data encryption, offers a full range of high-quality Datacryptor (Registered Trademark) encryptors for use in Government, Banking and Finance, R&D, and any application that needs secure data transmissions! Datacryptor highlights include: - Automatic/manual key changes - Generates and stores up to 400 keys - Easy to manage and program - Centarlized of front-panel operation - Protects Dial-up, Leased Line, or Shared Packet Transmissions - Up to E-1 rates - DES and proprietary algorithms - ANSI X9.17 - FED-STD 1027 - RSA Public Key - And More! For more information on Racal-Datacom Datacryptors, return this card or call 1-800-RACAL-55." The address (should anyone be interested) is: Racal-Datacom ATTN: Pre-Sales Support 155 Swanson Road Boxborough, MA 01719-9980 (The small, black and white picture on the postcard reveals a small box, not unlike an external modem, with two key-locks on the front panel.)
