20120221618 | ENCRYPTION METHOD COMPRISING AN EXPONENTIATION OPERATION - A method and a device protected against hidden channel attacks includes a calculation of the result of the exponentiation of a data m by an exponent d. The method and the device are configured to execute only multiplications of identical large variables, by breaking down any multiplication of different large variables x, y into a combination of multiplications of identical large variables. | 08-30-2012 |
20140129604 | Cryptographic method comprising a modular exponentiation operation - The present invention relates to a method for performing an iterative calculation of exponentiation of a large datum, the method being implemented in an electronic device (DV1) and comprising calculations of squaring and multiplying large variables performed in parallel, by squaring (SB1) and multiplication (SM1) blocks, the method comprising steps of: while a temporary storage buffer memory is not full of unused squares, triggering a calculation by the squaring block for a bit of the exponent, when the squaring block is inactive, storing each square provided by the squaring block in the buffer memory, if the bit of the corresponding exponent is on 1, and while the buffer memory contains an unused square, triggering a calculation by the multiplication block concerning the unused square, when the multiplication block is inactive. | 05-08-2014 |
20140355758 | METHOD OF GENERATING PRIME NUMBERS PROVEN SUITABLE FOR CHIP CARDS - The invention relates to a method for generating a prime number, implemented in an electronic device, the method including steps of calculating a candidate prime number having a number of bits, using the formula: Pr=2P·R+1, where P is a prime number and R is an integer, applying the Pocklington primality test to the candidate prime number, rejecting the candidate prime number if it fails the Pocklington test, generating the integer from an invertible number belonging to a set of invertible elements modulo the product of numbers belonging to a group of small prime numbers greater than 2, so that the candidate prime number is not divisible by any number of the group, the prime number P having a number of bits equal, to within one bit, to half or a third of the number of bits of the candidate prime number. | 12-04-2014 |
20140358980 | METHOD OF GENERATING PROVEN PRIME NUMBERS SUITABLE FOR BEING IMPLEMENTED IN A SMART CARD - The invention relates to a method for generating a prime number, implemented in an electronic device, the method including steps of generating a prime number from another prime number using the formula Pr=2P·R+1, where P is a prime number having a number of bits lower than that of the candidate prime number, and R is an integer, and applying the Pocklington primality test to the candidate prime number, the candidate prime number being proven if it passes the Pocklington test. According to the invention, the size in number of bits of the candidate prime number is equal to three times the size of the prime number, to within one unit, the generated candidate prime number being retained as candidate prime number only if the quotient of the integer division of the integer by the prime number is odd. | 12-04-2014 |

20150089956 | METHOD OF EXHAUST GAS TREATMENT FOR A GAS TURBINE SYSTEM AND EXHAUST GAS TREATMENT ASSEMBLY - The invention relates to a method for operating a gas turbine system, wherein the gas turbine system includes a compressor, a combustor, a heat recovery steam generator, a scrubber, a direct contact cooler. The method includes introducing the scrubbing fluid discharged from the scrubber into the direct contact cooler, contacting the scrubbing fluid in the direct contact cooler with the exhaust gas discharged from the heat recovery steam generator in order to remove a portion of nitrogen oxide therefrom; feeding the exhaust gas discharged from the direct contact cooler into the compressor. With the technical solution of the present invention, nitrogen oxide in the exhaust gas is reduced to a certain extent by means of used scrubbing fluid from the scrubber. This solution may improve the efficiency in reduction of nitrogen oxide with a simple and feasible manner. | 04-02-2015 |
