    摘要: A method of encrypting data is provided. The method includes dividing data in packet units into N data blocks; generating an initial counter value using a random number used for generating an encryption key for encrypting the data blocks; generating N counter values by increasing the initial value by a predetermined value N times and encrypting the N counter values using the encryption key; and performing an exclusive OR operation on the N encrypted counter values and the N data blocks.

    摘要: A method and apparatus for effectively managing a plurality of licenses are provided. The method includes selecting a value, which corresponds to license information, from a Hash mapping table; selecting a node corresponding to the license information from a tree structure corresponding to the value; and searching for a license by using license location information contained in the node. The apparatus includes a Hash function processor which computes a first value corresponding to the license information using a Hash function; a controller which selects a tree structure corresponding to the license information based on the first value computed by the Hash function processor; a tree structure manager which selects a node corresponding to the license information from the tree structure; and a storage unit which stores the license.

    摘要: Provided are a method and apparatus for controlling transmission of content data. In the method, a communication channel is initially established to transmit the content data, the content data is transmitted through the established communication channel, verification is performed a plurality of times to determine whether the content data is transmitted within an acceptable transmission range, and whether to continue the transmission of the content data is determined according to the verification result. Accordingly, when a client moves to a location outside a predetermined acceptable transmission range in a wireless environment, a server stops transmission of the content data. In addition, content data can be continuously transmitted regardless of interference caused by a temporary obstacle between a server and a client.

    摘要: A watermarking apparatus for embedding a watermark in a digital image, an apparatus for extracting watermark information from a watermarked image using a public key having a plurality of secret keys, and an apparatus for identifying whether a watermarked image generated by embedding a watermark in each region using a unit secret key is a copy of contents. The watermarking apparatus includes: a watermark generating unit that divides the digital image into a plurality of regions, assigns predetermined secret keys to each of the divided regions, respectively, and generates a watermark for each of the divided regions using the corresponding secret key; and a watermark embedding unit that generates a watermarked image for the digital image by embedding the watermarks in the corresponding regions, respectively, and combines the watermark-embedded divided regions. Since different kinds of keys are used when watermarking and extracting watermarked information, the watermark can be protected from illegal attacks.
