Kind Code:
A1
Abstract:
Disclosed is a received-data authentication method which makes it possible, in a digital broadcast receiver, to simplify authentication processing performed for verifying the trustworthiness of an application requiring authentication, and thereby reduce the delay in display of the application. The method comprises: determining, on the basis of application identification information, whether a received application requiring authentication is an application received for the first time; and, when the received application requiring authentication is determined to not be an application received for the first time, executing authentication processing with respect to the received application requiring authentication as a whole.
