    摘要: A mobile apparatus and method for displaying an Augmented Reality (AR) in the mobile apparatus. The mobile apparatus captures an image of a current environment of the mobile apparatus, displays the image, detects mapping information corresponding to the current environment from among mapping information stored in the mobile apparatus, maps a three-dimensional (3D) Graphical User Interface (GUI) of detected mapping information onto the displayed image, based on a relative location relationship between the detected mapping information, and adjusts a display status of the 3D GUI, while maintaining the relative location relationship between the detected mapping information.

A content using apparatus includes a receiver which receives a transport packet including content in at least one packet and a secret set, which includes an integrity check key generated for determining the integrity of the content, and extracts the secret set by processing the transport packet, a storage unit which stores the secret set, a controller which uses the secret set to determine whether each packet having the content maintains integrity, and a data processing unit which processes the at least one packet if the at least one packet is determined to be maintaining integrity. Accordingly, when content is transmitted, the integrity of the content can be checked using only a small amount of transmission data and a small amount of computation.

    摘要: Provided is a method of transmitting content keys to nodes arranged in a hierarchical structure which includes a plurality of node groups each including a predetermined number of the nodes. In this method, revoke information that includes identifiers of revoked node groups in the hierarchical structure, the total number of independent revoked nodes, and identifiers of the independent revoked nodes is generated. The revoked node groups are node groups consisting of only revoked nodes, and the independent revoked nodes are revoked nodes not belonging to any of the revoked node groups. Then, encrypted content keys are obtained by encrypting content keys using broadcast encryption, by using an encryption key set that has a form that cannot be generated using a decryption key set that the revoked nodes possess, and a set of encrypted content keys is generated. Thereafter, the revoke information and the set of the encrypted content keys are transmitted to all of the nodes arranged in the hierarchical structure.
