New TrustedFirmware Discord Server

by Don Harbin

Hi All, Note you may have received another instance of this note but when I attempted to send to all TF ML's simultaneously it seemed to fail, so sending to each one at a time. Sorry about that. :/ We've created a Discord Server for real time chats/sharing. This solution comes at no cost to the project, is set up with channels for each project, includes a #general channel, and supports direct 1-1 chats between members, all with the goal of improving collaboration between trustedfirmware.org developers. We encourage all to join! :) Instructions for joining can be found on the TF.org FAQ page <https://www.trustedfirmware.org/faq/>. See you all there and please don't hesitate to reach out if you have any questions! Don Harbin TrustedFirmware Community Manager don.harbin(a)linaro.org

Does mbedtls support x509 certificates signed wih ED448 algorithm?

by Bahadır Maktav

Hi, I am trying to use a certificate with its public key algorithm is NIST P-384 and its signature algorithm is ED448. I am working on ESP board with IDF framework which supports mbedtls. But when I am trying to use that certificate, I got error message about 'MBEDTLS_ERR_X509_UNKOWN_SIG_ALG'. So, I thought that maybe mbedtls does not support certificates which signed with ED448.

Does mbedTLS TLS1.3 only support PSK?

by Thompson, Jeff

I've got mbedTLS 3.1.4 and want to use TLS 1.3. My handshake fails very early because I don't have any Pre-Shared Keys. Does mbedTLS TLS1.3 only support PSKs, or can I still use generated session keys as does TLS 1.2? If so, how?

Silly python problem when building on MacOS

by Christian Huitema

Hello, I am trying to build MbedTLS on a Mac, as part of a project to support MbedTLS in the "picoquic" implementation of QUIC. I have a small problem, probably something of my making. I have cloned the repo on an "mbedtls" directory, created a "build" subdirectory, and from there run"cmake ..", which worked fine, and then tried to run "make", which fails in "generating psa_crypto_driver_wrapper.c" when trying the python script "generate_driver_wrappers.py" because it cannot find the python module "jsonschema". I tried to solve that by installing that module using "pip", and test programs running python3 do find the "jsonschema". Calling print(jsonschema.__file__) shows the module is installed in my user directory: /users/christianhuitema/Library/python3.9/lib/python/... Is there a simple way to fix that? -- Christian Huitema

Certificate Revocation

by ahmed bouzid

Hello, I'm currently engaged in a project where I'm utilizing mbedtls for the management of certificates. Within this project, I'm aiming to integrate a revocation feature using Certificate Revocation Lists (CRLs). However, my search for resources on how to effectively implement a comprehensive certificate revocation process using mbedtls has unfortunately yielded no productive outcomes. I am concerned about how to first create a crl file and sign it using my self-signed CA, how to revocate a certificate if we need to revocate it, and how to update the CRL, then when parsing the cert how to detect that this certificate has been revocated. ( I am using LPCXpresso55S16 as a client and raspberry pi as a server and I am doing all with coding). Thank you in advance for your support. Best regards, Ahmed.

Custom MBEDTLS_CONFIG_FILE with CMake subproject

by mickael.bonjour＠cysec.com

Hello, I need some help to setup mbedtls as a CMake subproject, I added it as a subdirectory in my CMakeLists. However, I can't figure out how to use my own config file for mbedtls (MBEDTLS_CONFIG_FILE option to the file I want as a config file). When I put my custom config file to the include folder of mbedtls in the place of the original mbedtls_config.h file it works wel,l but it's not a future-proof option for me, is there anyone that could help me with this setup ?

Missing PSA wrapper for MAC verify

by Ruchika Gupta

Hi, I have noticed that PSA driver wrapper function is missing for single part MAC verify function. In the current implementation, it calls the MAC compute wrapper and does the comparison using mbedtls_psa_safer_memcmp. The hardware I am working on allows the complete process to be offloaded to it. Can we have an option for the same in wrapper layer for PSA for MAC verify ? Regards, Ruchika

PSA crypto drivers

by Ruchika Gupta

Hi, I am currently working on PSA driver for our SoC's security crypto-processor. This processor needs to do some handling when a key is destroyed. In the current implementation in mbedTLS, I don't see a driver wrapper function available in psa_destroy_key(). Is there a specific reason for not having wrapper for driver function available for psa_destroy_key() ? Another query pertaining to the tests in the testsuite in mbedTLS. I was exploring if I could reuse the tests for the crypto-processor implementation. Have these been written with this kind of reuse in mind ? Basically I would like the ability to add driver location to the cases. The few cases I have looked at for psa seem to be very specific. Any pointers/suggestions if anyone is reusing this test suite to test their specific PSA drivers? Regards, Ruchika

mbedTLS hardware cryptography support

by Achraf BENLETAIFA

Hi, i wanted to ask if the hardware accelerators and TRNG of the Hardware Security Engine (HSE) of NXP S32K3XX microcontrollers are supported by the mbedTLS Library ? because i can't find it in the "MBEDTLS HARDWARE CRYPTOGRAPHY SUPPORT" list. Best regards, Ben

Hi Antonio, Thanks a lot for your answer ! Looking at the MbedTLS github link you sent (and the one therein) - https://github.com/Mbed-TLS/mbedtls/issues/6228 PSA: separate driver initialization with a nicer fixed ordering - https://github.com/Mbed-TLS/mbedtls/issues/6007 Define the PSA subsystem initialization interface in Mbed TLS it seems that for the best would be indeed to provide feedback to the MbedTLS/PSA team such that TF-M could just run the adequate psa_* functions. Thanks !

Hi Rehan, This looks like a non-PSA standardized feature specific to mbed TLS. We don't have any platform in TF-M that requires such setup/teardown so I can't comment from experience, but to me it looks like this would be an mbed TLS specific feature that needs to be hooked underneath the service and into the library. The most natural choice would be indeed to have them as part of the psa_crypto_init() and lower functions, but at this stage I think is not possible to implement this without patching the source code (i.e. there are no options to allow this at build time in TF-M, at least). Note also that mbed TLS has a on open ongoing issue to better define the initialisation sequence for the various operations in psa_crypto_init(): PSA: separate driver initialization with a nicer fixed ordering · Issue #6228 · Mbed-TLS/mbedtls (github.com)<https://github.com/Mbed-TLS/mbedtls/issues/6228> It might be a good place to start to provide feedback regarding this particular aspect of custom platform initialisation if is not being considered there. To conclude, if you want to propose a patch for TF-M to allow such functions to be plugged in (in the meantime that mbed TLS agrees on the long term course of action), I will be happy to review it. Thanks, Antonio ________________________________ From: Rehan Malak via TF-M <tf-m(a)lists.trustedfirmware.org<mailto:tf-m@lists.trustedfirmware.org>> Sent: Friday, July 7, 2023 13:15 To: tf-m(a)lists.trustedfirmware.org<mailto:tf-m@lists.trustedfirmware.org> <tf-m(a)lists.trustedfirmware.org<mailto:tf-m@lists.trustedfirmware.org>> Subject: [TF-M] mbedtls_platform_setup/teardown in TF-M ? Dear TF-M developers, I am currently adapting a basic MbedTLS / PSA Crypto example such that it would run on the NS side with TF-M doing the crypto. At the end, this is very similar to this psa_sign_verify_message_test from the NS crypto test suite : https://git.trustedfirmware.org/TF-M/tf-m-tests.git/tree/test/secure_fw/sui… But my build config of MbedTLS has MBEDTLS_PLATFORM_SETUP_TEARDOWN_ALT enabled because I have a custom mbedtls_platform_setup / mbedtls_platform_teardown. And I can't see any place in TF-M where mbedtls_platform_setup/mbedtls_platform_teardown are called : ? -> mbedtls_platform_setup ? -> mbedtls_platform_teardown At first, I tried to put this code into the psa_driver_wrapper_init/psa_driver_wrapper_free but I have a similar problem : tfm_crypto_engine_init -> psa_crypto_init -> psa_driver_wrapper_init ? -> mbedtls_psa_crypto_free -> psa_driver_wrapper_free Is there any cmake/Kconfig option or any C macros to hook TF-M initialization/shutdown with mbedtls_platform_setup/mbedtls_platform_teardown without patching TF-M ? If not, could mbedtls_platform_setup be called here ? https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/secure_fw/… or is there a nicer way of doing this ? (btw, I am currently experimenting on qemu mps2-an521) Thanks for any advice ! 🙂 Best regards, Rehan MALAK Intrinsic ID

Python version requirements

by Gilles Peskine

Hello, This is a question for integrators and packagers of Mbed TLS, especially if you're integrating the library in some embedded OS or BSP. To build, configure and test Mbed TLS, we use Python for several purposes: * To configure the library with scripts/config.py, unless you use the default configuration or write your own configuration from scratch. * To generate some configuration-independent library source files, but only if you use the development branch, not if you use a release or an LTS branch. * To generate some glue code for PSA drivers, if you use PSA drivers and don't write the glue code by hand. * To generate the unit test source files. * (We have many more maintenance and test scripts but they're out of scope here.) (Python is not necessary, and will remain unnecessary, to configure and build the library with a given set of hardware drivers, so that a typical BSP will not have to depend on Python.) For each of these purposes, how problematic is it if we require a recent version of Python? We're currently planning to drop support for older versions of Python as soon as they become unsupported upstream (so officially dropping 3.8 now — although right now all scripts still work on 3.5). This includes versions of Python that are still shipped in e.g. Linux distributions that are themselves officially supported. Is there demand for supporting older Python versions for some scripts? Also, how problematic is it if some of these purposes require third-party Python packages? Best regards, -- Gilles Peskine Mbed TLS developer
