Hi Jamie, Sorry for the trouble. According to your description, the violation error is caused by non-secure test cases. is it correct? The error message is dumped by tfm_secure_api_error_handler(). It is called multiple times in Library model routine. Can you please help narrow the step in which tfm_secure_api_error_handler() is called? Besides, do you mind trying if IPC model can work on your board?

Re: [TF-M] Questions on Musca-B1 SE implementation - code size analysis

by Thomas Törnblom

Hello Suresh, I have no access to a B1 target, which is the reason no IAR port exists. Cheers, Thomas 24 juli 2021 kl. 22:39 skrev Suresh Marisetty via TF-M <tf-m(a)lists.trustedfirmware.org>: Hi, One of the requests that I have is how the code size differs between GCC and IAR for the Musca-B1 SE build. However, it appears from the documentation that IAR is not supported on Musca-B1. So, I am wondering if anybody can provide some insight on the size from IAR. And here are the TF-M image sizes as of now with GCC in release mode: SE: ~185 KiB code flash and ~63 KiB RAM Host: ~22 KiB code flash and ~16 KiB RAM (a few more KiB needed for the images in flash for image header and trailer if loaded by mcuboot) IAR? thanks Suresh Marisetty Infineon Semiconductor Corporation From: David Hu <David.Hu(a)arm.com> Sent: Sunday, July 4, 2021 11:37 PM To: Marisetty Suresh (CYSC CSS ICW SW SSE) <Suresh.Marisetty(a)infineon.com>; Mark Horvath <Mark.Horvath(a)arm.com> Cc: nd <nd(a)arm.com>; tf-m(a)lists.trustedfirmware.org Subject: RE: Questions on Musca-B1 SE implementation - code size analysis Caution: This e-mail originated outside Infineon Technologies.

What ciphers are supported in medium vs. large (I see the size of the code bloats up almost twice from 30 to 60K approx) – observation from size of libmbedcrypto and libcrypto_service_cc312 – any clear documentation on this or a link would be helpful (besides code review) 2. When the SE is built for the large profile, assume it also includes “Software countermeasures against physical attacks” since it is offloading to the CC-312 * Is there a way to build the large profile without physical attack counter-measures? * While library are these countermeasures implemented in (libmbed or lib_cc312)? 1. On our initial analysis, for a medium profile these two libraries appears to be 30K-33K in size each and is this in the right ballpark? (with minsizerel) I assume the code size increase is due to additional cipher support + physical attack countermeasures.

Please check FIH design document: https://tf-m-user-guide.trustedfirmware.org/docs/technical_references/tfm_p… Compared to Profile Medium, Profile Large enables more cryptographic algorithms support and FIH library. It may also include more configurations of higher isolation.

What ciphers are supported in medium vs. large (I see the size of the code bloats up almost twice from 30 to 60K approx) – observation from size of libmbedcrypto and libcrypto_service_cc312 – any clear documentation on this or a link would be helpful (besides code review) 2. When the SE is built for the large profile, assume it also includes “Software countermeasures against physical attacks” since it is offloading to the CC-312 * Is there a way to build the large profile without physical attack counter-measures? * While library are these countermeasures implemented in (libmbed or lib_cc312)? 3. On our initial analysis, for a medium profile these two libraries appears to be 30K-33K in size each and is this in the right ballpark? (with minsizerel) I assume the code size increase is due to additional cipher support + physical attack countermeasures. Correct me otherwise. thanks Suresh Marisetty Infineon Semiconductor Corporation From: Mark Horvath <Mark.Horvath(a)arm.com<mailto:Mark.Horvath@arm.com>> Sent: Friday, May 14, 2021 5:30 AM To: Marisetty Suresh (CYSC CSS ICW SW SSE) <Suresh.Marisetty(a)infineon.com<mailto:Suresh.Marisetty@infineon.com>>; tf-m(a)lists.trustedfirmware.org<mailto:tf-m@lists.trustedfirmware.org> Cc: nd <nd(a)arm.com<mailto:nd@arm.com>> Subject: Re: Questions on Musca-B1 SE implementation Caution: This e-mail originated outside Infineon Technologies.

Hi Suresh, Yes, by default the cc312 acceleration is turned on at build time for SE, and the algorithms will be handled by HW instead of the SW implementation. If you would like to use SW crypto instead you can pass the HW_ACCELERATOR="OFF" flag to cmake when building the SE TF-M instance. And here are the TF-M image sizes as of now with GCC in release mode: SE: ~185 KiB code flash and ~63 KiB RAM Host: ~22 KiB code flash and ~16 KiB RAM (a few more KiB needed for the images in flash for image header and trailer if loaded by mcuboot) Best regards, Mark ________________________________ From: David Hu <David.Hu(a)arm.com<mailto:David.Hu@arm.com>> Sent: Thursday, May 13, 2021 5:26 AM To: Suresh.Marisetty(a)infineon.com<mailto:Suresh.Marisetty@infineon.com> <Suresh.Marisetty(a)infineon.com<mailto:Suresh.Marisetty@infineon.com>>; Tamas Ban <Tamas.Ban(a)arm.com<mailto:Tamas.Ban@arm.com>>; tf-m(a)lists.trustedfirmware.org<mailto:tf-m@lists.trustedfirmware.org> <tf-m(a)lists.trustedfirmware.org<mailto:tf-m@lists.trustedfirmware.org>>; Mark Horvath <Mark.Horvath(a)arm.com<mailto:Mark.Horvath@arm.com>> Cc: nd <nd(a)arm.com<mailto:nd@arm.com>> Subject: RE: Questions on Musca-B1 SE implementation Hi @Mark Horvath<mailto:Mark.Horvath@arm.com>, Could you please help take a look at the following questions about Musca-B1 SE?

A few questions: 1. Is it correct to state that for the SE, the PSA RoT services do not have any software Crypto implementation, but leverage from CC-312? 2. What is the size of the TFM on the host (M33) with only PSA RoT service proxy with redirection to SE 3. Just trying to understand the TFM image size requirements on M33 vs. SE 4.

Also, does the TFM profile small/medium/large map to this at all or is it different from them. Also, what’s are the estimated latencies of boot on SE with all the Flash accesses, etc. https://www.trustedfirmware.org/docs/Musca-B1-Secure-Enclave-Solution.pdf https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/platform/e… Any info on this would be appreciated. thanks Suresh Marisetty Infineon Semiconductor Corporation
