Detailed Description

Driver for the Secure Crypto Engine (SCE9) on RA MCUs.

Overview

This module provides SCE functions in protected mode.

Note
For a detailed description of the different SCE9 operating modes, refer to Application Note R11AN0498.

HW Overview

Crypto Peripheral version Devices
SCE9 (Protected mode) RA4M2, RA4M3, RA6M4, RA6M5

Features

The SCE module supports for the following features.

Configuration

Clock Configuration

This module does not require a specific clock configuration.

Pin Configuration

This module does not use I/O pins.

Usage Notes

Getting Started: Creating a SCE Protected Mode Project

Start by creating a new project in e² studio or RASC. On the Stacks tab, add New > Security > SCE Protected Mode. For information on how to install and update secure keys, refer to the Application Note R11AN0496.

Reducing intialization time

The SCE intialization sequence can be modified to support a smaller subset of features and allow for a shorter intialization period. This is particularly useful in cases where startup time is important and the cryptographic features that are required are known in advance. The current fast boot configuration option supports the cryptographic primitives requried by MCUBoot including:

Limitations

Usage of R_SCE_ECDSA_secp384r1_SignatureGenerate/Verify

The SCE does not support SHA-384 in hardware, so the APIs listed below require the user to create a SHA-384 function for signature generation and verification. To use the APIs listed below, enable SCE_USER_SHA_384_ENABLED on RA Smart Configurator and prepare a function called SCE_USER_SHA_384_FUNCTION. The interface of SCE_USER_SHA_384_FUNCTION, which is called by the following APIs, is described below.

SCE_USER_SHA_384_FUNCTION()

uint32_t SCE_USER_SHA_384_FUNCTION(uint8_t *message, uint8_t* digest, uint32_t message_length)

SHA-384 hash calculation is performed for an area extending the number of bytes specified by the argument message_length from the address specified by the argument message. The calculation result should be stored at the address specified by the argument digest.

Parameters
message[in] Start address of message
digest[in,out] address for storing hash calculation result (48 bytes)
message_length[in] Effective byte count of message
Return values
0Hash value stored successfully.
othersStoring of hash value failed.

)

The R_SCE_AES128GCM_EncryptUpdate() function encrypts the plaintext specified in the second argument, plain, in GCM mode using the values specified for wrapped_key and initial_vector in R_SCE_AES128GCM_EncryptInit(), along with the additional authentication data specified in the fifth argument, aad. Inside this function, the data that is input by the user is buffered until the input values of aad and plain exceed 16 bytes. After the input data from plain reaches 16 bytes or more, the encryption result is output to the ciphertext data area specified in the third argument, cipher. The lengths of the plain and aad data to input are respectively specified in the fourth argument, plain_data_length, and the sixth argument, aad_length. For these, specify not the total byte count for the aad and plain input data, but rather the data length to input when the user calls this function. If the input values plain and aad are not divisible by 16 bytes, they will be padded inside the function. First process the data that is input from aad, and then process the data that is input from plain. If aad data is input after starting to input plain data, an error will occur. If aad data and plain data are input to this function at the same time, the aad data will be processed, and then the function will transition to the plain data input state.
