초록

This paper presents new hardware implementation of the ECC(Elliptic Curve Cryptography) algorithm that is improved in speed and stability. We proposed new datapath that changed square's position so that we can reduce required number of cycles for addition operation between two points by more than 30%. We used Massey-Omura parallel multiplier adopted Normal basis for fast scalar multiplications. Also the use of the window non-adjacent form (WNAF) method can reduce addition operation of each other different points. We implemented ECC system with GF($2^{196}$), and this system was designed and verified by VHDL.
