    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: An apparatus and a method for generating random data are provided to generate random data by using a PUF(Physically Unclonable Function) logic. CONSTITUTION: A first logic gate performs the logical operation of first data and second data. A second logic gate performs the logical operation of the first data and the second data. The second logic gate has a different type from the first logic gate. A logic operation value selecting unit selects either a logic operation value of the first logic gate or the logic operation value of the second logic gate by using predetermined reference date. A logic operation value controlling unit inputs a selected logic operation value as the second data into the first logic gate and the second logic gate. A data output unit outputs the selected logic operation value into random data.
