Abstract:
A system for the secure transmission and reception of information which uizes pseudo values of phase and amplitude of speech signals, which are related to the original values by specific algorithms. These pseudo values of phase and amplitude are encrypted separately and then transmitted. A similar system is used to process the received signals to obtain the original information.
