Abstract�� Elliptic curve digital signature arithmetic can achieve high security using a shorten key, so it is very suitable to realize this arithmetic on smart card. The characteristic of hardware accelerator was introduced. In order to increase the executive speed of elliptic curve digital signature arithimeitc, projective coordinates was adopted in stead of affine coordinates. The executive time was provided .The result indicates that the arithmetic can work availably, comparing with RSA and DSA ,the executive time of elliptic curve digital signature arithmetic is reduced greatly.
Keywords�� elliptic curves   affine coordinate transformation   projective transformations   smart card   COS   digital signature
