Abstract:
We consider the system of exchange of information with the help of phase-shifted signals. The input signals are Walsh sequences are then deformed sequence known only to the subscribers. For the disclosure of the transmitted information necessary to determine the sequence of distorting Data protection is provided by a third party due to the group properties of Walsh sequences. Chance disclosure does not exceed 1 / n, where n is the length of Walsh sequences. Examples are given.
