Abstract (en)
[origin: WO2010009917A1] The invention relates to a method for implementing a characteristic-2-multiplication of at least two input bit strings, each having a number N of bits, by means of a processor unit suitable for carrying out an integer multiplication, comprising the following steps: a) generating at least one sequence of a number K of zero bits, using K?{1,...,N}, by means of a first transformation of the respective input bit string to at least one predetermined position in the respective input bit string for generating at least one first intermediate bit string; b) linking the at least two first intermediate bit strings by means of the integer multiplication of the processor unit for generating at least one second intermediate bit string; and c) transforming the at least one second intermediate bit string by means of a second transformation for generating a result bit string.
