Abstract
A method for managing license information for playback of content, includes transmitting certificate information of a storage device to a license serve, updating a certificate revision list received from the license server on the basis of the certificate information, receiving encrypted license information allowing the content to be played through a first session established between the storage device and the license server, the first session being identified by session identification information, and decrypting the encrypted license information and storing the decrypted license information to a secure region.
