RSA API 参考

RSA

wm_device_t *wm_drv_rsa_init(const char *dev_name)

Initialize RSA driver.

备注

This API must be called before all other RSA API can be called

参数:

dev_name – RSA device name

返回:

• NULL: failed

• others: RSA driver device

int wm_drv_rsa_deinit(wm_device_t *dev)

Deinitialize RSA driver.

参数:

dev – RSA driver device

返回:

• WM_ERR_SUCCESS: succeed

• WM_ERR_INVALID_PARAM: invalid argument

• others: failed

int wm_drv_rsa_expt_mod(wm_device_t *dev, mbedtls_mpi *X, const mbedtls_mpi *A, const mbedtls_mpi *E, const mbedtls_mpi *N)

This function implements the large module power multiplication algorithm. X = A^E mod N.

参数:

• dev – [in] Pointer to the RSA device structure.

• X – [out] Pointer to a bignumber. used to store the result of A^E mod N

• A – [in] Pointer to a bignumber. base

• E – [in] Pointer to a bignumber. exponent

• N – [in] Pointer to a bignumber. modulus

返回:

0
