An approach is proposed to design of a robust data transfer channel for telecommunication networks that is based on the desired bits spectrum spreading and their additional scrambling by using two pseudo noise coding sequences derived from primitive polynomials of eighth and fifteenth degrees. Further information protection is offered to be achieved by deploying four 32768 chip-long pseudo noise coding sequences, instead of one, with 128 cyclic shifts each. It is proven that selection of a scrambling sequence and its cyclic shift according to a secret algorithm on a frame-by-frame basis helps substantially improve performance of the telecommunication channel in terms of protection against interception while preserving its useful properties. Research results permit to claim that the designed telecommunication channel could be used in noise immune and concealed telecommunication networks.
