ABSTRACT:
An apparatus for producing multiple independent binary bit streams from a single underlying key stream. The output from a high speed key generator is fed serially into a multistage shift register. At preselected intervals, the contents of the register are parallel dumped and logically combined with a stored binary word to generate a binary bit which is gated to an output. A plurality of linearly independent binary bit streams result when the register contents are combined with a plurality of linearly independent binary words, one word for each output.
