| Summary: | In this paper, a fast hardware architecture for elliptic curve cryptography computation in Galois Field GF(p) is proposed. The architecture is implemented for 160-bits, as its data size to handle. The design adopts projective coordinates to eliminate most of the required GF(p) inversion calculations replacing them with several multiplication operations. The hardware is intended to be scalable, which allows the hardware to compute long precision numbers in a repetitive way. The design involves four parallel scalable multipliers to gain the best speed. This scalable design was implemented in different versions depending on the area and speed. All scalable implementations were compared with an available FPGA design. The proposed scalable hardware showed interesting results in both area and speed. It also showed some area-time flexibility to accommodate the variation needed by different crypto applications. |
