1. An information delivering system for delivering predetermined first information and predetermined second information from a delivering station to a receiving terminal, wherein the delivering station comprises:
- a ciphering part ciphering the second information for each predetermined time interval;
a first information sending out part including deciphering information for the predetermined time interval part of the second information ciphered by said ciphering part in the first information and sending it out; and
second information sending out part sending out the relevant predetermined time interval part of the second information ciphered by said ciphering part after said first information sending out part sends out the first information including the relevant deciphering information, and wherein after receiving the first information and the second information, the receiving terminal deciphers the predetermined time interval part of the second information with the use of the relevant deciphering information included in the first information, and provides the thus-deciphered information for a user.
