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.

CONSTITUTION: An analysis waveform storage unit(210) stores and collects analysis target waveform data which is used for analyzing sub-channels by leakage information collecting apparatus. A elimination point calculation apparatus(220) grasps elimination point for the waveform data by using the clock frequency of an analysis target apparatus and waveform collecting frequency for the analysis target data stored in the analysis target waveform data storage unit. The elimination point calculation apparatus outputs the size of the waveform data. A sub-channel analysis apparatus(230) analyzes a sub-channel by using the waveform data outputted by the elimination point calculation apparatus.

PURPOSE: A sub channel analyzing device is provided to measure an electromagnetic wave which is highly related to a security operation for sub channel analysis. CONSTITUTION: A waveform measurement unit(120) measures a power signal of an analysis board(140). An electromagnetic wave measurement unit(130) measures an electromagnetic wave signal of the analysis board. An analysis unit(110) analyzes a sub channel using the measured electromagnetic wave signal. The electromagnetic wave measurement unit obtains an electromagnetic wave signal which is scanned by the analysis board. The electromagnetic wave measurement unit measures the electromagnetic wave signal at a point where the scanned electromagnetic wave signal is highly related to the power signal.
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.
Abstract:
PURPOSE: A waveform noise eliminating method using a noise model for sub channel analysis and a sub channel analyzing device using the same are provided to guarantee objectivity of an analysis result using a noise model for sub channel analysis. CONSTITUTION: A database is built for a noise pattern of noises in which waveform data are generated(S410). Waveform data are collected from an external waveform collecting device. A noise mode to be applied to the waveform data is selected in a database for the noise pattern(S423). A noise is eliminated by applying the selected noise model to the collected waveform data(S430).
