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: PURPOSE: The effectiveness of calculation is enhanced by reducing the number of key line segment receiving method is the element in the sensor networks. CONSTITUTION: Two sensor node Sis and Sj give and take the share heat Gc and the Gc consisting of 2 numbers, G1i, G2i, G1j, G2j which is not 0 of the finite field(S300). The g1j received between the sensor node Si and Sj, and the g2j value are appointed to the specific location within the Gc(S302). The g1j received between the sensor node Si and Sj, and the g2j value are appointed to the specific location within the Gc(S304).

Abstract: An image file format for storing digital evidence from computer storages and a recoding medium thereof are provided to enable a user to input variable additional information for image file freely by using metadata without the restriction of type or format of inner data. A file header unit(10) provides encryption algorithm information of an image file format structure, and a meta data unit(20) having a variable length provides an encryption related key value. Original data are recorded at a segment data unit(30). The segment data unit indicates the bad sector location inside the original data in bit map, and a file termination unit(40) provides the location information of the segment data unit.
