Gretacoder 715
Highly secure encryptor for SIC bank transfers - this page is a stub

Gretacoder 715 was a highly secure data encryption and authentication system, developed in the late 1980s by Gretag Data Systems (formerly: Gretag) in Regensdorf (Switzerland). The device was developed especially for TELEKURS and was successfully used for many years by the Swiss Inter­bank Clearing Net (SIC) for secure and trusted money transfers between all major Swiss banks. The device uses the Data Encryption Standard (DES) in Cipher Block Chaining Mode (CBC) [A].

The image on the right shows a typical Greta­coder 715, as it is shown on the cover of the 1989 full-colour brochure [B].
