Hi,
I see "CRYPTO_TFM_BUILTIN_KEYS_DRIVER" mentioned in the documentation but where is "CRYPTO_BUILTIN_KEYS" defined? And should those target props be formatted as "${prop}"?

Our requirement is to send email securely from our embedded device running on STM32H7 processor. There's an SMTP client application (implemented using Mbed TLS library) running on this device, which will send emails to the recipient via custom/public email server such as smtp.gmail.com. We are planning to use S/MIME email certificate from the one of the Trusted CA, for encryption of the email message and authentication of the client/server. We learnt that each S/MIME email certificate support only one email address, but we will be having multiple devices running on the field and each device will have unique email address from which email will be sent. Getting S/MIME email certificate for device will not be feasible, is there any better way we can handle this scenario effectively. Your response to this problem is greatly appreciated.
Thank you,

Hi,
On the last tech forum (June 22) we started discussion on multicore hybrid platforms.
By this mail I’d like to follow up and continue offline analyses on new use-cases and requirements for TF-M design update.
The recorded session is available here: https://linaro-org.zoom.us/rec/share/yseF-mYwUTtHHPkQJQO6IEv72xCd0Lz1pQQecc…, Passcode: 5s=Npv=w
and slides: https://www.trustedfirmware.org/docs/tech_forum_20230622_Hybrid_platforms.p…
The current plan is to take time, think on the use-cases and map them on requirements. With more thought and materials, we will have another session about September time to define our needs in the support of new type of platform.
Please share your thoughts in reply.
Thanks,
Anton
Hi,
We are planning to update the mechanism on partition interface ABI selection in IPC model.
In current Implementation, cross call ABI is chosen in Isolation Level 1, and SVC call ABI is chosen in Isolation Level 2&3.
However, interfaces are actually the bridge between SPM and caller partitions. If one partition shares the same boundary with SPM, cross call ABI is the choice; while if one partition does not share the same boundary with SPM, a SVC ABI is the proper choice.
But, a simple comparison between two boundary values cannot be used for checking if the two boundaries are the same one - these values might be encoded with bit fields and contains more info than memory regions. Hence the comparison should be done by who generated them - the isolation HAL implementation in platform sources.
So here comes to the following design:
1. In HAL function tfm_hal_bind_boundary, encode p_ldinf into boundary value, so that there is no need to pass both p_ldinf and boundary value to switch boundary.
1. Implement a HAL function to compare boundaries and switch boundary if needed.
tfm_hal_status_t tfm_hal_switch_boundary(
uintptr_t target_boundary,
uintptr _t current_boundary,
uint32_t compare_only, /* 0: Switch boundary if they are different, 1: Only compare whether the boundaries are different and do not switch */
uint32_t* compare_result); /* Tell the caller whether the boundaries are different */
1. Select correct type of ABI when processing metadata of partition based on boundary.
void prv_process_metadata(struct partition_t *p_pt)
{
...
tfm_hal_switch_boundary(SPM_BOUNDARY, p_pt->boundary, 1, *compare_result);
if (compare_result == 1) {
p_rt_meta->psa_fns = &psa_api_svc;
} else {
p_rt_meta->psa_fns = &psa_api_cross;
}
...
}
Please let us know if you have any suggestion.
Thanks,
Xinyu
Hi All,
I wanted to let you know that next Thursday, July 27th, the TF-A Tech Forum
will be hosting a presentation on OpenCI and MISRA presented by Paul
Sokolovski of Linaro and Roberto Bagnara from Bugseng. MISRA is being
enabled on both TF-A and TF-M in OpenCI, so sending this out to both lists
since users in both domains may be interested in the session.
Meeting time and dial up info can be found in the TF community calendar
located here: https://www.trustedfirmware.org/meetings/
