Abstract
Update firmware is stored as one binary file. The binary file includes firmware data necessary for operating a controller unit and root certificate data necessary for a printer apparatus to establish secure communication with a content server. Specific information in the root certificate data is extracted from the update firmware, and the extracted specific information is used to update a management table of the root certificate provided in a RAM. With this configuration, it is possible for an information processing apparatus to reliably acquire and update the root certificate data without greatly changing the original functional configuration.
