Debug authentication using password

The debug authentication with password method reuses protocol defined by document
authentication response message customized with a new field that carries the password.
The following figure describes the debug authentication messages sequence when using the password method to
trigger a full regression.

Debug authentication using a certificate chain

5.4.1

Sequence diagram

The STM32H5 debug authentication service uses a certificate format and certificate chain defined by
document [1].
Figure 6 describes the debug authentication messages sequence when using the certificate method (in this case,
only one root certificate is used).

STM32H5 debug authentication protocol description
Command name
This command is used to provide the
debug token and additional credentials
as part of a complete authentication
response to the target.
Not used in STM32H5 debug
authentication service
The lock debug command restores the
device's debug access controls to the
locked state, given its current life cycle
state.
