Abstract:
1. A device management system comprising: a peripheral device; a management server configured to manage device information of the peripheral device; and a terminal communicable with the management server, wherein the peripheral device comprises: a first generation unit configured to generate key obtaining information for obtaining from the management server an authentication key for generating signature information to be used in transmission of the device information; and a first transmission unit configured to transmit a request for obtaining the authentication key that contains the key obtaining information and device identification information of the peripheral device, to the management server, wherein the terminal comprises: an obtaining unit configured to obtain the key obtaining information from the peripheral device; and a second transmission unit configured to transmit the key obtaining information obtained by the obtaining unit to the management server, and wherein the management server comprises: a first reception unit configured to receive the key obtaining information from the terminal; a registration unit configured to register the key obtaining information received from the terminal while associating the key obtaining information with the device identification information of the peripheral device and the authentication key managed by the management server; a second reception unit configured to receive the obtaining request from the peripheral device; a determination unit configured to determine whether a key obtaining information that is registered while being associated with the device identification information contained in the received obtaining request from the terminal matches a key obtaining information contained in the received obtaining request; and a response unit configured to, if the determination unit determines that they match each other, transmit the authentication key associated with the key obtaining information received from the terminal to the peripheral device as a response to the obtaining request.
