3 TOE preparative procedures
This section provides useful information for ensuring that the target of evaluation (TOE) has been received and
installed in a secure manner as intended by the developer.
• Secure acceptance: procedures to check the product to be prepared.
• Secure preparation of the operational environment: procedures to set up the environment needed to
manage and prepare the final product.
• Secure installation: procedure to program and configure the product to be prepared.
• Tera Term connection preparation procedure: procedure to configure the Tera Term tool before starting to
prepare the product.
3.1 Secure acceptance
Secure acceptance is the process in which the user securely receives the TOE and verifies its genuineness (the
integrity and authenticity of all its components). The TOE is distributed as an MCU device.
To ensure that the MCU is not manipulated during TOE delivery, the Integrator must verify that the user flash
memory is virgin (reading 0xFF at any address location with STM32CubeProgrammer). For more details on
STM32CubeProgrammer, refer to [UM2237].
During the secure acceptance process, it is the responsibility of the Integrator to obtain the correct software
package as described in
The Integrator accepts a microcontroller part of the STM32U5 series by reading, with STM32CubeProgrammer,
the DBGMCU_IDCODE register value as defined in
Table 1.
