Abstract
A modular arithmetic method and microelectronic apparatus therefore, operative to perform a sequence of interleaved Montgomery type multiplications and squaring operations, involves performing a sequence of modular multiplications and squarings using only a single carry save adder. Each multiplication is operative to perform the equivalent of three natural integer multiplication operations using an anticipatory device to determine a Y.sub.0 value, such that a result is an exponentiation.
