A reconfigurable arithmetic logic unit for elliptic curve cryptosystems over GF (2/sup m/)

In this paper the authors presented an arithmetic logic unit (ALU) for elliptic curve cryptosystems over GF (2/sup m/). The novelty of these ALU is the inclusion of a hardware inversion operation, which is as fast as a multiplication. So faster algorithms can be used for the computation of kP. Although a serial multiplication and inversion was used, a faster computation than other parallelized hardware implementations was achieved.
