PSA crypto driver - KEY LOCATIONS

by Ruchika Gupta

Hi, For the crypto accelerator, we are developing for our SoC, we have a use-case where the same driver can support multiple/range of KEY LOCATIONS. We want a mechanism such that, the a common function in driver is called which can then take the necessary option based on the key location. The way jsons are currently structured, what I understand is that for every key location, we will need to create a separate json with a different driver prefix. This would lead to a lot of code duplication for us. For eg { to define 3 locations X, Y and Z , I need to create 3 json files -> these all refer to same crypto sub-system I my case} #define TEST_DRIVER_X_OPAQUE_DRIVER_ID #define TEST_DRIVER_Y_OPAQUE_DRIVER_ID #define TEST_DRIVER_Z_OPAQUE_DRIVER_ID Switch (key_location) Case x: Test_driver_x_ opaque_import_key(); break; Case y: Test_driver_y_ opaque_import_key(); break; Case z: Test_driver_z_ opaque_import_key(); break; This is resulting in a lot of code duplication and overhead. What we want to have the flexibility to achieve is : #define TEST_DRIVER_OPAQUE_DRIVER_ID Switch (key_location) Case x: Case y: Case z: Test_driver_opaque_import_key(); If we can support multiple locations from a driver json file for a given driver, this issue would be resolved. This would give the driver writers flexibility on how and where they want to handle the locations. Please let us know your views on the same. Regards, Ruchika

psa_raw_key_agreement does not like PSA_ALG_ECDSA(PSA_ALG_SHA_256)

by Christian Huitema

I am not sure I completely understand the PSA API for key exchange. I have been creating a private key, exporting the public key, passing that successfully to the peer, obtaining the peer's public key, and I want to use psa_raw_key_agreement to obtain the shared secret. But it fails in: if (!PSA_ALG_IS_KEY_AGREEMENT(alg)) { status = PSA_ERROR_INVALID_ARGUMENT; goto exit; } The value of "alg" is 0x06000609, computed as PSA_ALG_ECDSA(PSA_ALG_SHA_256). That's probably wrong, but I do not know why... -- Christian Huitema

Output format of mbedtls_ecdh_make_params does not play well with TLS 1.3

by Christian Huitema

In TLS 1.3, one half of an ECDH exchange is defined as a "key entry", coded as: struct { NamedGroup group; opaque key_exchange<1..2^16-1>; } KeyShareEntry; The opaque data is typically encoded as a one byte format (e.g., 0x04, no compression), and then the encoding of either one or two points: 32 bytes for one point with CURVE25519, 64 bytes for two points with SECP256R1. The encoding for the "public key" output of mbedtls_ecdh_make_params is different: 1 byte of length, followed by 2 bytes of curve ID, followed by the raw encoding of the point or points. The related encoding of the server public key output of mbedtls_ecdh_make_public is also different: 1 byte of length, followed by 2 bytes of curve ID, followed by the raw encoding of the point or points. To make that work, I need some reformatting: strip out 3 bytes for the client public key, write a single 0x04 byte instead; strip out one byte from the key-exchange data received at the server and write 3 bytes of length and curve ID instead. Also, make sure to reset the strings to the unmodified value before calling mbedtls_ecdh_calc_secret, which probably means maintaining two copies, thus twice the memory. This is a bit messy, and probably unnecessary. The extra parameters "length" is already passed through the API (the &olen argument) and the "group_id" could easily be passed as well. Or maybe I am looking at the wrong API... -- Christian Huitema

TLS handshake with AWS IoT MQTT broker seems to succeed and then is terminated by the broker

by Roger Sala

I am developing an AWS IoT MQTT client on STM32H723 using FreeRTOS 10.3.1, LwIP 2.1.2 and MbedTLS. My first attempt used MbedTLS 2.16.2 and it mostly works except that sometimes, seemingly related to the timing of the network I'm using, it fails when my client fails to send out anything after the Client Key Exchange message and then the server responds with a Close Notify as follows: "Time","Source","Destination","Protocol","Length","Info" "0.000000","10.24.108.94","54.157.158.237","TLSv1.2","418","Client Hello" "0.016460","54.157.158.237","10.24.108.94","TLSv1.2","150","Server Hello" "0.002777","54.157.158.237","10.24.108.94","TLSv1.2","685","Certificate" "0.000000","54.157.158.237","10.24.108.94","TLSv1.2","438","Server Key Exchange, Certificate Request, Server Hello Done" "0.976521","10.24.108.94","54.157.158.237","TLSv1.2","1006","Certificate, Client Key Exchange" "0.014853","54.157.158.237","10.24.108.94","TLSv1.2","61","Alert (Level: Warning, Description: Close Notify)" When it works it looks like this: "Time","Source","Destination","Protocol","Length","Info" "0.000000000","10.0.0.11","54.84.254.130","TLSv1.2","418","Client Hello" "0.017495225","54.84.254.130","10.0.0.11","TLSv1.2","150","Server Hello" "0.001743255","54.84.254.130","10.0.0.11","TLSv1.2","685","Certificate" "0.000022282","54.84.254.130","10.0.0.11","TLSv1.2","392","Server Key Exchange" "0.000004428","54.84.254.130","10.0.0.11","TLSv1.2","100","Certificate Request, Server Hello Done" "2.606030441","10.0.0.11","54.84.254.130","TLSv1.2","1326","Certificate, Client Key Exchange, Certificate Verify, Change Cipher Spec, Encrypted Handshake Message" "0.027421478","54.84.254.130","10.0.0.11","TLSv1.2","105","Change Cipher Spec, Encrypted Handshake Message" "0.000971482","10.0.0.11","54.84.254.130","TLSv1.2","193","Application Data" "0.075384354","54.84.254.130","10.0.0.11","TLSv1.2","87","Application Data" The last two "Application Data" messages are the MQTT connect and connect ACK, So before I filed a bug report, I upgraded to MbedTLS 2.28.4. The good news is that this client always (seems) to successfully negotiate the TLS handshake, but after receiving the first encrypted "Application Data" (connect), the broker immediately sends and "Encrypted Alert", which I'm taking to be a Close Notify because a TCP FIN follows shortly thereafter. The Wireshark capture of the 2.28.4 handshake looks almost exactly like the successful 2.16.2 handshake: "Time","Source","Destination","Protocol","Length","Info" "0.000000000","10.0.0.11","44.195.98.16","TLSv1.2","336","Client Hello" "0.018450117","44.195.98.16","10.0.0.11","TLSv1.2","150","Server Hello" "0.000524146","44.195.98.16","10.0.0.11","TLSv1.2","685","Certificate" "0.000003168","44.195.98.16","10.0.0.11","TLSv1.2","392","Server Key Exchange" "0.000002995","44.195.98.16","10.0.0.11","TLSv1.2","100","Certificate Request, Server Hello Done" "2.517148776","10.0.0.11","44.195.98.16","TLSv1.2","1329","Certificate, Client Key Exchange, Certificate Verify, Change Cipher Spec, Encrypted Handshake Message" "0.016572792","44.195.98.16","10.0.0.11","TLSv1.2","60","Change Cipher Spec" "0.000007326","44.195.98.16","10.0.0.11","TLSv1.2","99","Encrypted Handshake Message" "0.001500778","10.0.0.11","44.195.98.16","TLSv1.2","193","Application Data" "0.031014646","44.195.98.16","10.0.0.11","TLSv1.2","85","Encrypted Alert" ... except for the "Encrypted Alert" from the broker that leads to the closing of the session. I'm hoping someone has an explanation of the behavior I'm seeing and can suggest a path forward for me. Another data point is the fact that the client with MbedTLS 2.28.4 can successfully authentic and negotiate a TLS handshake with a mosquitto broker I'm running locally using self signed certificates. ====================================================================== The information contained in this e-mail, including all of its attachments, is confidential and proprietary information of IPG Photonics and its affiliates and intended only for the use of the individual or entity named above.

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

mbedtls_pk_verify verify report MBEDTLS_ERR_RSA_VERIFY_FAILED

by yang ming

When `mbedtls_pk_verify` is used to verify digital signatures generated by openssl, the MBEDTLS_ERR_RSA_VERIFY_FAILED error occurs, openssl Specifies the command used to generate a certificate: ```bash openssl md5 -sign private.key -out sign test.md ``` But when I use `mbedtls_pk_sign(&pk_pri_ctx, MBEDTLS_MD_MD5, md, 0, sign_info, sizeof(sign_info), &size, mbedtls_ctr_drbg_random, &ctrl_drbg)` Generating the signature and using `mbedtls_pk_verify` results are successful, Print the signatures generated by mbedtls are not found to be the same as those generated by openssl. Please help。 mbedtls version: ```c #define MBEDTLS_VERSION_STRING "3.4.0" #define MBEDTLS_VERSION_STRING_FULL "mbed TLS 3.4.0" ``` openssl version: ```c OpenSSL 1.1.1 11 Sep 2018 ```
