    摘要: 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.

    摘要: A method of transporting an encrypted stream of multimedia content is provided. In the method, when a packet contains data of a predetermined length including selected data from pieces of data corresponding to the multimedia content and a header, key information, and first time information from among pieces of information included in a selected packet from among at least one packet are received, and encryption information is determined from the key information and the first time information, according to a key derivation function. The first time information is variable with time. The at least one packet including data corresponding to the multimedia content is encrypted using the encryption information. The at least one encrypted packet and the key information are transported.
