In this paper, a dual-field ellipticcurvecryptographicprocessor is proposed to support arbitrary curves within576-bit in dual field. Besides, two heterogeneous function units are coupled with the processor for the parallel operations in finite field based on the analysis of the characteristics of ellipticcurvecryptographic algorithms. To simplify the hardware complexity, the clustering technology is adopted in the processor. At last a fast Montgomery modular division algorithm and its implementation is proposed based on the Kaliski's Montgomery modular inversion. Using UMC 90-nm CMOS 1P9 M technology, the proposed processo occupied 0.86-mm can perform the scalar multiplication in 0.34 ms in GF(p) and 0.22 ms in GF(2)respectively. Compared to other ellipticcurvecryptographicprocessors, our design is advantageous in hardware efficiency and speed moderation.
