/* AES-CTR 128-bit
* Parameters:
* Return:
* sgx_status_t - SGX_SUCCESS or failure as defined in sgx_error.h
* Inputs:
* sgx_aes_128bit_key_t *p_key - Pointer to the key used in encryption/decryption operation
* uint8_t *p_src - Pointer to the input stream to be encrypted/decrypted
* uint32_t src_len - Length of the input stream to be encrypted/decrypted
* uint8_t *p_ctr - Pointer to the counter block
* uint32_t ctr_inc_bits - Number of bits in counter to be incremented
* Output:
* uint8_t *p_dst - Pointer to the cipher text. Size of buffer should be >= src_len.
