Abstract

Inherent terminal identification information and a terminal unique key are stored in an on-board terminal, and server-side terminal identification information and a server-side terminal unique key, which are same information as the above terminal identification information and terminal unique key are stored in a server. And, the on-board terminal transmits the terminal identification information to the server via a communication terminal, and the server performs terminal authentication according to the server-side terminal identification information, and if the authentication is success, transmits encrypted software for the on-board terminal of which authentication was success to the communication terminal. The communication terminal transmits the encrypted software to the on-board terminal, and the on-board terminal obtains a software unique key, which is encrypted by the server-side terminal unique key by the server, via the communication terminal, decrypts the encrypted software using the software unique key, and installs it.

Claims

1. An information distribution system including a communication terminal, an on-board terminal which can be connected to the communication terminal by wire or wireless, and a server, wherein:

the on-board terminal is provided with;

an on-board terminal identification information storage section for storing terminal identification information inherent to the on-board terminal,

an authentication information generation section for generating the on-board terminal authentication information including the terminal identification information stored in the on-board terminal identification information storage section, and

an inter-terminal equipment communication section for transmitting the authentication information generated by the authentication information generation section to the communication terminal,

the communication terminal is provided with;

an inter-equipment communication section which can be connected to the on-board terminal by wire or wireless,

a storage section for storing the on-board terminal authentication information received by the inter-equipment communication section, and

a server communication section which can transmit the on-board terminal authentication information stored in the storage section to the server,

the server is provided with;

a terminal communication section for receiving the on-board terminal authentication information from the communication terminal,

an authentication information verification processing section for authenticating the on-board terminal authentication information received by the terminal communication section,

a last authentication timestamp storage section for storing the timestamp when authentication is success by the authentication information verification processing section, and

an authentication information management section for storing the timestamp, when the authentication is success by the authentication information verification processing section, into the last authentication timestamp storage section, and

the server, when it receives the on-board terminal authentication information from the communication terminal, authenticates the on-board terminal authentication information using a timestamp when the on-board terminal authentication information is authenticated by the authentication information verification processing section, and a timestamp stored in the last authentication timestamp storage section.

2. The information distribution system according to claim 1, wherein:

the server is provided with a software delivery section for delivering software for the on-board terminal, and

the authentication information manage tent section stores the timestamp, when delivery of the software for the on-board terminal is completed, into the last authentication timestamp storage section.

3. The information distribution system according to claim 1, wherein:

the server is provided with a cryptographic processing section for encrypting and delivering the on-board terminal software, and a software unique key storage section for encrypting the on-board terminal software, and

the authentication information management section stores timestamp when delivery of the software unique key to the last authentication timestamp storage section is completed.

4. The information distribution system according to claim 1, wherein:

the server is provided with an on-board terminal software management database for storing the last authentication timestamp for each piece of the on-board terminal software, and

the authentication information verification processing section manages an expiration date of the on-board terminal software using a last authentication timestamp inherent to the on-board terminal software stored in the software management database for each piece of the on-board terminal software.

5. The information distribution system according to claim 4, wherein the server can manage the number of delivery times of the on-board terminal software.

6. The information distribution system according to claim 5, wherein the server can manage the number of delivery times of the software unique key.

7. The information distribution system according to claim 1, wherein the on-board terminal authentication information includes a random number.

8. The information distribution system according to claim 1, wherein a numerical value which is commonly possessed by the on-board terminal and the server is used for the on-board terminal authentication information.

9. An on-board terminal which can be connected to a communication terminal by wire or wireless, wherein:

the on-board terminal is provided with;

an on-board terminal identification information storage section for storing terminal identification information inherent to the on-board terminal,

an authentication information generation section for generating the on-board terminal authentication information including terminal identification information stored in the on-board terminal identification information storage section, and

an inter-terminal equipment communication section for transmitting the authentication information generated by the authentication information generation section to the communication terminal, and

the authentication information generation section, when the on-board terminal and the communication terminal are connected, generates authentication information using information for determining that authentication information is usable one time and identification information of the on-board terminal, and transmits the authentication information to a server via the communication terminal.

10. A communication terminal capable of communicating with a server and an on-board terminal, comprising:

a storage section for storing the on-board terminal authentication information received from the on-board terminal, and

a server communication section which transmits to the server the on-board terminal authentication information stored in the storage section and a request to obtain a software unique key for decrypting the encryption software, and receives the on-board terminal encryption software and the software unique key when it is judged by the server that the decrypting key can be delivered.
