ABSTRACT:
Apparatus for the secure transmission of digital data signals is disclosed in which fixed logic gates and a variable bank of logic gates are used in an encoding circuit to scramble the digital data signals with two enciphering words. The resulting scramble signals are then further scrambled by a programmable multiplexer and the output transmitted to a decoding circuit. The decoding circuit, which is responsive to the signal from the encoding circuit, then recreates the original digital data signal.
