    • An apparatus and method for computing a SHA-1 hash function value are provided. The apparatus includes a first register unit including a plurality of registers that store a first bit string of predetermined lengths for generation of a hash function value; a second register unit storing input data in units of second bit strings with predetermined lengths, and sequentially outputting the second bit strings; a third register unit performing an operation on the first bit string of the plurality of registers and the second bit strings output from the second register unit so as to generate and store a third bit string, and updating first-bit string of the plurality of registers based on the third bit string; and an adding unit combining the first bit string stored in the first register unit, the first bit string of the third bit string stored in the third register unit, and the original initial values stored in the first register unit so as to obtain a hash function value. Accordingly, it is possible to reduce the size of the apparatus and stably compute a hash function value at a high speed.

    • A rijndael block cipher apparatus including an operational unit that efficiently performs a round operation for encrypting/decrypting a rijndael block cipher and an encryption/decryption method thereof are disclosed. The rijndael block cipher apparatus is mounted in a mobile terminal such as a cellular phone and a PDA or a smart card, which requires a high-rate and small-sized cipher processor, and can encrypt and decrypt important data that requires security at high speed and perform the round operation with respect to upper 64 bits and lower 64 bits which are divided from 128-bit input data. Thus, the cipher apparatus can reduce the time required for encryption/decryption of the rijndael block cipher and the size of the apparatus.
