函数说明

ecc_ecfp_aff_to_jac()

td_s32 ecc_ecfp_aff_to_jac	(	const drv_pke_ecc_point *	in,
		const drv_pke_data *	mod_p,
		pke_ecc_point_jac *	out
	)

trans coordinate system from affine to jacobin, before call this API, you should have set mont_1_p and const_0 into ecc_addr_mont_1_p and ecc_addr_const_0. (ecc_addr_px, ecc_addr_py) -> (ecc_addr_cx, ecc_addr_cy, ecc_addr_cz).

参数

in	the input point in affine system.
mod_p	the modulur.

返回

td_s32 TD_SUCCESS or others.

ecc_ecfp_mul_naf()

td_s32 ecc_ecfp_mul_naf	(	const drv_pke_ecc_curve *	ecc,
		const drv_pke_data *	k,
		const drv_pke_ecc_point *	p,
		const drv_pke_ecc_point *r	CIPHER_CHECK_WORD
	)

R = k * G, point multiplication.

参数

ecc	input ecc curve param.
k	the scalar.
p	the input point.
r	the output point.
CIPHER_CHECK_WORD	ifdef SEC_ENHANCE, the value is XOR result of parameters, otherwise it doesn't exist.

返回

td_s32 TD_SUCCESS or others.

ecc_ecfp_mul_naf_cal()

td_s32 ecc_ecfp_mul_naf_cal	(	td_u32	work_len,

k	the scalar.

返回

td_s32 TD_SUCCESS or others.

get_random_key()

td_s32 get_random_key	(	const td_u8 *	n,

	)

Get the random key object range in [1, n-1]

参数

n	range.
size	the byte length of number n.
rand	the output random data.
CIPHER_CHECK_WORD	ifdef SEC_ENHANCE, the value is XOR result of parameters, otherwise it doesn't exist.

返回

td_s32 TD_SUCCESS or others.
