| Abstract: | The arithmetic solutions over elliptic curves and VLSI implementation of a coprocessor for elliptic curve cryptosystems are studied in this paper. Based on a new projective reference frame, the algorithms for adding and doubling points to solve the point multiplication problem are presented and a new optimum scheme for the memory is also discussed. A new VLSI architecture of the coprocessor based on the above algorithms is given. The results of the simulation indicate that the speed of point multiplication is 155 operations with 50 MHz clock cycle. |
