Abstract
Techniques are provided for performing modular arithmetic on a key composed of many bits. One circuit implementation includes a distributor, one or more lookup tables and a plurality of adders. The distributor segments the key into a plurality of partitions. Each partition is based on a polynomial expression corresponding to a fixed size key. Each of the bits contained within the partitions are routed on a partition basis to one or more lookup tables, the routed bits acting as indices into the one or more tables. The lookup tables store precomputed values based upon the polynomial expression. The outputted precomputed values from one or more lookup tables are outputted to the plurality of adders. The plurality of adders add the bits from a portion of the routed partitions and the outputted precomputed values from the one or more lookup tables to form the binary residue.
