Abstract

　送信局と受信局との間の通信内容が傍受されることを防止する。 　送信局１０は、受信局２０から測定用信号を受信し、元の基準となる信号から伝搬路における歪を測定する。送信局１０は、測定した変動量に基づいて、送信する秘匿信号が受信局２０で正しく受信できるように歪補償を行う。送信局１０は、秘匿信号の存在を盗聴局５０に知られにくくするため、歪補償した秘匿信号に雑音を付加するとともに、秘匿する必要がないカバー信号を付加する。秘匿信号がカバー信号に対して雑音程度と見なせる程度に秘匿信号及びカバー信号の電力を調整する。受信局２０は、送信局１０が送信した秘匿信号を受信し、カバー信号を除去し、元の秘匿信号を取り出す。
