Abstract
Methods and apparatus for Montgomery multiplication process a multiplier operand in k-bit radix-digits, wherein k corresponds to a radix r=2. A multiplicand operand and a modulus are processed word by word, and then additional bits of the multiplier operand are selected for processing. In a radix r=8 example, the multiplier operand is processed in 3 bit radix-8 digits. A processing kernel is configured to preprocess the modulus and/or the multiplier operand so that at least some values can be obtained from lookup tables.
