Abstract : The present invention relates broadly to voice transmission systems and in particular to an automatic authentication apparatus for a voice transmission system. It has been shown by the experience gained in Viet Nam and earlier that intrusions into voice communications circuits by unfriendly parties was largely successful because of the inability or unwillingness of our troops to use authentication procedures to identify the caller on those voice circuits. The process of authentication is used to assure a receiver station that the calling party is providing legitimate information or orders. The present invention solves the problem of intrusion into military communications by enemy forces. The bogus use of call signs of our stations by enemy troops is well known. Only another identification means will improve the credibility of the station identification. This intrusion can be prevented by the conventionally performed authentication procedures when used.
