Problems solved by technology

[0009] However, consider the case where it is difficult to import public key certificates in each device in advance
For example, when the device manufacturer and service provider are different, it is difficult to import the public public key certificate issued by the service provider into the device when manufacturing the device

Embodiment approach 1

[0030] Describes how to import electronic certificates to communication devices.

[0031] figure 1 It is a block diagram of the device authentication system 100 in Embodiment 1.

[0032] according to figure 1 The configuration of the device authentication system 100 in Embodiment 1 will be described.

[0033] The device authentication system 100 (an example of a device certificate providing system) is a system for introducing an electronic certificate into the communication device 400 so that the communication device 400 can communicate using the electronic certificate. Electronic certificates are also called public key certificates. The public key certificate certifies the owner (eg, communication device 400) of the public key.

[0034] The device authentication system 100 includes a security GW 200 (GW: gateway), a device information server 300 , a communication device 400 , and a certification authority server 110 . They communicate via the network 109 .

Abstract

The invention discloses a device certificate provision apparatus, a device certificate provision system, and a device certificate provision program. A device ID inquiry unit (241) transmits a device ID request including an IP address (293) as the communication address of a destination and receives, from a communication device, the communication device identifier thereof. A device ID determination unit (242) determines whether the communication device identifier is the same device identifier as a device ID (291). If the communication device identifier is the same device identifier as the device ID (291), a public key acquisition unit (243) acquires a device public key (492) from the communication device, and a device certificate transmission unit (245) transmits a device certificate (494) including the device public key (492) to the communication device.

Description

technical field [0001] The invention relates to the technology of importing electronic certificates into communication equipment. Background technique [0002] Patent Document 1 discloses a technique related to an authentication system including a server, a certification authority (CA), a device, and a registration terminal. [0003] In this technique, in order for a device to connect to a server, a dummy public key certificate not associated with device information and a true public key certificate associated with device information are used as described below. [0004] First, the registration terminal obtains a pseudo public key certificate from the certification authority, and writes the obtained pseudo public key certificate into an IC card (IC: Integrated Circuit). Write the secret key and public key of the device in the IC card. [0005] Then, the user connects the IC card to the device, and the device uses its own device information and the fake public key certifica...
