摘要： According to one embodiment, an encryption device includes a storage unit, an input unit, first to fourth partial encryption units, a generation unit, and an output unit. The first partial encryption unit calculates first intermediate data from input plain data to store in the storage unit. The generation unit generates a round key, which is used in calculations for the first intermediate data and N-th intermediate data, from the secret key. The second partial encryption unit calculates (i+1)th intermediate data from i-th intermediate data (i is smaller than N) and the round key to store in the storage unit. The third partial encryption unit performs an arithmetic operation including predetermined conversion for mixing the N-th intermediate data, and calculates (N+1)th intermediate data to store in the storage unit. The fourth partial encryption unit obtains encrypted data by performing an arithmetic operation including inverse conversion of the conversion on the (N+1)th intermediate data.

摘要： According to one embodiment, a first shift amount calculation unit counts the number of continuous zeros from a less significant bit toward a more significant bit of an intermediate result of a computation of Montgomery multiplication result z and calculates a first shift amount. A second shift amount calculation unit counts the number of continuous zeros from a less significant bit toward a more significant bit of redundant-binary-represented integer x and calculates a second shift amount. An addition/subtraction unit calculates the intermediate result by adding/subtracting, with respect to the intermediate result which has been bit-shifted by the first shift amount, the integer p, and the integer y which has been bit-shifted by the second shift amount. An output unit outputs, as the Montgomery multiplication result z, the intermediate result when the sum of the first shift amounts is equal to the number of bits of the integer p.

摘要： In a switching power supply apparatus, multiplier 9 multiplies error voltage Verr generated in voltage error amplifier 8 and input voltage Vin to generate first threshold signal Vth1 in-phase with and similar to input voltage Vin and having an amplitude proportional to error voltage Verr. Second threshold signal generator circuit 14 generates second threshold signal Vth2 from first threshold signal Vth1. Switching device 7 is turned on and off so that the inductor current may change between first and second threshold signals Vth1 and Vth2. The switching frequency is detected and the proportional factor of first and second threshold signals Vth1 and Vth2 is changed to control the average switching frequency almost at a constant value for reducing the high frequency noises and the switching losses. The switching power supply apparatus facilitates reducing the noises and losses, improving the power factor thereof, and preventing the response performances thereof from being impaired.

摘要： An error voltage Verr, being a difference between DC output voltage Vout and output reference voltage Vref, and an input voltage Vin are multiplied to produce first threshold voltage signal Vth1 in phase with and similar to input voltage Vin and proportional to Verr. Second threshold voltage signal Vth2 is produced from first threshold voltage signal Vth1.
