Method and system for importing and exporting configurations

A system for importing and exporting device parameters, comprising:

• a manufacturer server for generating a manufacturer public key and a manufacturer private key;
• and
• a plurality of commodities each storing a manufacturer certificate generated according to the manufacturer public key,
• wherein the manufacturer server receives a client public key and signs the client public key according to the manufacturer private key so as to generate a manufacturer signature, and the plurality of commodities receives the manufacturer signature, the at least one setup parameter, and a client signature generated by signing the at least one setup parameter according to a client private key;
• wherein each said commodity verifies the manufacturer signature according to the manufacturer certificate stored in the commodity, the commodities which have passed the verification verify the client signature according to the manufacturer signature, and the at least one setup parameter is applied to the commodities which have passed the verification.

A system for importing and exporting device parameters, adapted to verify a plurality of commodities, comprising:

• a manufacturer server, comprising:
• a storing unit for storing a manufacturer public key and a manufacturer private key;
• a communication unit for receiving a client public key from a setup host;
• and
• a signature unit for signing the client public key according to the manufacturer private key to generate a manufacturer signature and sending the manufacturer signature to the setup host through the communication unit;
• and
• a computer program product executed by the setup host, comprising:
• a communication module for sending the client public key to the manufacturer server through a communication interface and receiving the manufacturer signature;
• a setup module for receiving at least one setup parameter through an input interface;
• and
• a signature module for signing the at least one setup parameter according to the client private key to generate a client signature and sending the at least one setup parameter, the client signature, and the manufacturer signature to the plurality of commodities through the communication module, respectively, so as for the at least one setup parameter to be applied to the commodities upon an affirmative verification of the manufacturer signature and an affirmative verification of the client signature.
