    Abstract: Disclosed is an encryption apparatus applying a KASUMI encryption algorithm. In the encryption apparatus, a round circuit is constructed through combination of an FL block with an FO block. The FL and FO blocks separate a secret key defined in the KASUMI encryption algorithm and provided from a secret key scheduler and 64-bit text data into 32-bit data, respectively, and perform specified encryption operation functions. The FO block is constructed through a multistage pipeline using a plurality of pipeline registers. The encryption apparatus has a low power consumption, and is small-sized in comparison to the conventional encryption apparatus using the MISTY or DES encryption algorithm. Also, the encryption apparatus can be applied to portable terminals and high-performance servers that require the low power consumption and the small size.

    Abstract: A 3D shape restoration method and a device of an object using multi-viewpoint image information are provided to obtain a realistic image by rendering restored results, thereby showing an excellent restoration quality for 3D shape restoration of a dynamic object. A silhouette and color extractor(104) inputs multi-viewpoint images for taking pictures of an object at various viewpoints. The silhouette and color extractor extracts silhouette information and color information. A visual hull restorer(106) configures a visual hull through silhouette intersection. A polygon approximation unit(108) moves along with a section of the visual hull. The polygon approximation unit approximates a sectional polygon to a geometric external form of the object by using the color information. A mesh structure generator(110) connects the approximated polygon in mesh structure. The mesh structure generator expresses a 3D geometric external form of the object.
