Abstract
The disclosure relates to decomposition of masked values in a cryptographically secure digital signing system. Example embodiments include a method of decomposing mod 44 an N bit Boolean share input (b'), where N>12, the method comprising: i) reducing (-) a number of bits in the Boolean share input (b′) by adding a lower 11:0 bits of the input (b′) to an upper portion of the input left shifted by 2 bits to provide a first intermediate result having M bits; ii) reducing (-) a number of bits of the first intermediate result by adding a lower 6:0 portion of the intermediate result to an upper portion left shifted by 2 bits and subtracted from a multiple of 44 to provide a second intermediate result and iii) adjusting (-) the second intermediate result by adding and/or subtracting 44 to provide an output having a value within an interval of 0:43, the output being a mod 44 representation of the input (b').
