Automatic data coding and decoding circuit for transmission system has digital code source in form of addressable memory to produce code independent of content of input clear text

摘要

In a typical application data (K) passes from the data input (Datenstrom Eingang) to a mixer (Hash) from which coded data (K') passes to the data output (Datenstrom Ausgang). The coding circuit produces a code key number (SN) and a key value (SK(SHN)) also a key hook number (SHN). A code number (C) is passed to the mixer to code the transmitted data.
