ABSTRACT:
The invention provides a digital data shuffling/de-shuffling system so that information data is not understood or deciphered by unauthorized third party. Included are a system for generating plural bits of digital data to be transmitted, a circuit network 7 having a plurality of input terminals #1 through #8 and output terminals #11 through #18 equal to the number of bits to be transmitted and a plurality of switching circuits S for selectively cross connecting or non-cross connecting between two lines out of a plurality of transmission lines a.sub.1 through a.sub.8 interconnecting the corresponding input and output terminals, and a control circuit P for controlling the plurality of switching circuits S. The control circuit P is controlled to shuffle the data applied to the input terminals #1 through #8 for providing the shuffled output from the output terminals #11 through #18.
