	R = u1 * G + u2 * Q. Before call this API, you should have set curve initial parameters into DRAM, which must include ecc_addr_mont_a, ecc_addr_mont_1_p, ecc_addr_const_1, ecc_addr_const_0.

函数说明

ecc_ecfp_mul_add()

td_s32 ecc_ecfp_mul_add	(	const drv_pke_ecc_curve *	ecc,
		const drv_pke_data *	u1,
		const drv_pke_data *	u2,
		const drv_pke_ecc_point *	q,
		const drv_pke_ecc_point *r	CIPHER_CHECK_WORD
	)

R = u1 * G + u2 * Q. Before call this API, you should have set curve initial parameters into DRAM, which must include ecc_addr_mont_a, ecc_addr_mont_1_p, ecc_addr_const_1, ecc_addr_const_0.

参数

ecc	input ecc curve param.
u1	the scalar.
u2	the scalar.
q	the input point(public key), which is in affine coordinate system.
r	the output point. result is in (ecc_addr_cx, ecc_addr_cy, ecc_addr_cz).
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.
