Secure communication system

摘要

A secure communication system comprising: a first cyclical pseudo-random noise generator comprising determinable variable starting point means and an output; transmitting means for transmitting said pseudo-random noise generator output; receiving means for receiving said transmitting means transmissions, said receiving means having an output; recycling storage means for storing said receiving means output; a second cyclical pseudo-random noise generator identical to said first pseudo-random noise generator having an output and a reset input, said receiving means output connected to said reset input; a correlator having a first input connected to said storage means and a second input connected to said second pseudo-random noise generator output and an output from said correlator; and timing means connected to said receiving means output and said correlator output for measuring time elapsed between any output of said receiver and said correlator.
