<p>A system and a method for updating software in real-time are provided to safely update the software used in a client connected through the network in real-time after authenticating a product and the client. A client terminal(100) generates a product authentication key and the first hash value based on a serial number of the software to be updated, transmits the product authentication key and the serial number to an authentication server(300), and requests an update server(400) to update the software if authentication is completed. The authentication server generates the second hash value based on the serial number and the product authentication key, and generates and transmits a service authentication key to the client terminal if the authentication is completed. In case that the first hash value is matched with the second hash value, the client terminal transmits the serial number and the product authentication key to the update server.</p> |
