Optimizing Multiprecision Multiplication for Public Key Cryptography.
Michael Scott, Piotr Szczechowiak · 2007
Abstract. In this paper we recall the hybrid method of Gura et al. for multi-precision multiplication [4] which is an improvement on the basic Comba method and which exploits the increased number of registers available on modern architectures in order to avoid duplicated loads from memory. We then show how to improve and generalise the method for application across a wide range of processor types, setting some new records in the process. Keywords: Multi-precision arithmetic. 1
