Abstract:
A method of checking revocation of a device and software, and transmitting data to a secure device and secure software whose keys have not been leaked is provided. The method includes receiving authentication information of a device requesting transmission of data, and authentication information of software accessing the data in the device; checking revocation of the device and the software, based on the received authentication information; and transmitting the data to the software of the device, when the device and the software are not revoked as a result of the checking. By doing so, during transmission of data, such as content or a license, it is possible to check security of a device and software being executed in the device, so that the data can be more safely transmitted.
