In signal transmission, the signal and a random number are transmitted and the random number is used for selecting the next transmission base. An unauthorized recipient does not know the base but has to make 2<SP>n</SP>-valued determination for error-correction code decoding so that his/her BER becomes greater than that of the authorized recipient. A difference between the BERs of the authorized recipient and the unauthorized recipient ensures the quantity of information that is safe from a viewpoint of information theory.  <P>COPYRIGHT: (C)2010,JPO&INPIT
