  • Method and apparatus for the exponentiation of large binary numbers in a residue class modulo N, particularly for encoding and decoding digitally-represented messages
    Patent number: 4532638
    Abstract: A method and apparatus provides for exponentiation of large binary numbers in a residue class modulo N, particularly for encoding and decoding digitally-represented messages, in which the exponentiation comprises repeated scoring/multiplication cycles with a residue formation. The method provides that, respectively, one squaring/multiplication operation and one residue formation operation are executed nearly time-parallel and that the respective residue formation is undertaken by multiplication with a determined matrix.
