Abstract

This paper introduces a scalable architecture for the Montgomery multiplication operation. There is no limitation on the maximum number of bits manipulated by the multiplier, and the selection of the word-size can be made according to the available area and/or desired performance. We give a general description of the new architecture, analyze the hardware organization for parallel computation, and discuss design tradeoffs which are useful to identify the best hardware configuration.
