Summary The performance of elliptic curve based
public key cryptosystems is mainly appointed by
the efficiency of the underlying finite field
arithmetic. This work describes a reconfigurable
finite field multiplier, which is implemented
within the latest family of Field Programmable
System Level Integrated Circuits from Atmel, Inc.
The architecture of the coprocessor is adapted
from Karatsubas divide and conquer algorithm and
allows for a reasonable speedup of the top-level
public key algorithms. The VHDL hardware models
are automatically generated based on an eligible
operand size, which permits the optimal
utilization of a particular FPSLIC device.
