Abstract:
A modular reduction device particularly for cryptography on elliptical curves. The device includes a Barrett modular reduction circuit and a cache memory in which the results of some precalculations are carried out. When the result is not present in the cache memory, a binary division circuit makes the precalculation and stores the result in the cache memory.
