Abstract

PROBLEM TO BE SOLVED: To considerably shorten a required time for communication in receiving the distribution of data through an internet system. SOLUTION: In a data communication method for receiving the distribution of desired data through the internet system, request communication from a terminal machine 1 to a server 4 is executed by wire communication. A key for cipher decoding is transmitted from the server 4 to the terminal machine 1 by the same line and data to be transmitted from the server 4 is ciphered so that it is decoded by the key and it is distributed by radio communication.

The terminal 1 has a receiving antenna 2 and is connected to a server 4 via a public telephone network 3. This server 4 has a transmitting antenna 5,
The key for decryption is transmitted to the terminal 1 that has made the request via the public telephone network 3, and required data encrypted so as to be decrypted by the key is transmitted from the transmission antenna 5. This key information, as well as information used as a normal decryption key, for example, may include time information such as frequency band information and decentralized scheme information for data transmission, transmission start time,
Further, data transmission may be performed by a time sharing method or an intermittent pulse train signal, and a time gate synchronization signal on the receiving side may be included. The “decryption key” referred to in this specification includes all such information.
Although omitted in the figure, a large number of terminals are connected to the public telephone network 3.

In this communication system, when the terminal 1 is operated to connect the terminal 1 to the server 4 via the public telephone line network 3 and a required request operation is performed, the server 4 makes a request. In addition to transmitting the decryption key of the data to the terminal 1 via the line, the encrypted desired data is transmitted from the transmission antenna 5. When the wirelessly transmitted data is received by the receiving antenna 2 of the terminal 1, a decryption circuit (not shown) of the terminal 1 receives the data based on the decryption key input through the public telephone network 3. Since the data is decrypted, the request data is decrypted and provided to the user.

There is no particular limitation on the radio frequency used, but it is desirable to use shortwave, ultrashortwave or ultrashortwave for transmitting and receiving a large amount of digital information in a short time. In this communication system, the transmitted data is updated every time it is transmitted, and a different decryption key is transmitted to the terminal every time a request is issued. It cannot be used on terminals other than the terminal that made the request.
