Abstract: Disclosed herein are a Gaussian sampling apparatus and method based on resistive RAM. The Gaussian sampling apparatus based on resistive RAM includes Resistive RAM (RRAM) in which a resistive switching layer is disposed between an upper electrode and a lower electrode, and a sampling controller, wherein the sampling controller is configured to perform an operation corresponding to an erase command of applying a reset voltage to the RRAM when a Gaussian error request is received from an outside of the Gaussian sampling apparatus, perform an operation corresponding to a program command of applying a set voltage to the RRAM after the operation corresponding to the erase command has been completed, perform an operation of reading resistance data from the RRAM, and provide a response to the outside of the Gaussian sampling apparatus by transmitting the resistance data of the RRAM as Gaussian error data.

Abstract: A low-power encryption apparatus and method are provided. The low-power encryption apparatus includes a mask value generation unit, a mask value application unit, a round key application unit, a mask operation unit, a shift operation unit, and a shift operation correction unit. The mask value generation unit generates a mask value M having the same bit length as input round function values. The mask value application unit generates first masking round function values by applying the mask value M. The round key application unit generates second masking round function values by applying round key values. The mask operation unit generates third masking round function values by performing a mask addition operation. The shill operation unit generates fourth masking round function values by performing a circular shift operation. The shift operation correction unit generates output round function values by performing an operation using the mask value M.

Abstract: Disclosed herein are a method for generating Gaussian error data using flash memory and an apparatus using the method. The method includes receiving a request to generate Gaussian error data and delivering an operation command to flash memory; generating Gaussian error noise based on a threshold voltage that is generated when the flash memory performs the operation command; and generating Gaussian error data so as to correspond to the Gaussian error noise and providing the same.
