[0140] figure 1 is an exemplary diagram simply showing the first embodiment.
[0141] A management server 7 that manages device authentication information is installed at the management center 3 and is used to encrypt the device authentication information before transmitting the encrypted device authentication information to the factory 5 .
[0142] The connecting means 10 are linked to the connectors of the CE equipment 9 by workers of the factory. The connection device 10 provides the device authentication information received from the management server 7 to the CE device 9 in its encrypted state as it is.
[0143] The CE device 9 includes an embedded writing module for decrypting the encrypted device authentication information and storing the decryption result in the storage unit.
[0144] As mentioned above, the writing module decrypts the encrypted device authentication information received from the connection device 10 and stores the decryption result in the storage u...

[0334] Figure 10 It is a demonstration diagram simply showing the second embodiment
[0335] In the case of this embodiment, in the process of generating device authentication information, by using the same logic in the management server 7 and CE device 9, information serving as a source for generating device authentication information is converted into device authentication information. For example, source information is encrypted so that device authentication information is generated in the same encryption process using the same encryption key in the management server 7 and CE device 9 .
[0336] First, the management server 7 transmits source information to the factory 5, and converts the source information into device authentication information in a process of generating device authentication information.
[0337] On the other hand, in the factory 5 , the source information is supplied to the CE equipment 9 via the connection device 10 . Subsequently, the CE device 9 co...
