SE050C2HQ1 middle ware integration issue

daisuke2 — Mon, 03 Nov 2025 22:34:19 GMT

I am trying to integrate middle ware for SE050C2HQ1 on imx8mp custom board.

I used 'SE-PLUG-TRUST-MW_04.07.01.zip' from nxp portal site and build with cmake flag as bellow

---------------------------

-DCMAKE_BUILD_TYPE=Debug \
-DPTMW_Host=iMXLinux -DPTMW_HostCrypto=OPENSSL -DPTMW_SMCOM=T1oI2C \
-DPTMW_SE05X_Auth=PlatfSCP03 -DPTMW_SCP=SCP03_SSS -DPTMW_Applet=SE05X_A \
-DPTMW_SE05X_Ver=07_02

when i trying to run 'ex_ecc', i am keep getting error like bellow

----log----------------------

App :INFO :Running ex_ecc
App :INFO :Using PortName='/dev/i2c-2' (CLI)
App :INFO :PlugAndTrust_v04.07.01_20250519

sss :ERROR:Could not set SCP03 Secure Channel
App :ERROR:sss_session_open failed

App :ERROR:!ERROR! ret != 0.

------------------------------------

I thought that my scp3-key 'scp03_keys.bin' might be problem, so i tried 'se05x_MandatePlatformSCP' and 'se05x_Delete_and_test_provision'.

But keep getting "unknown key type" error and fails.

It seems that Applet in SE050C2H is new than "SE-PLUG-TRUST-MW_04.07.01.zip".

Is there any newer "SE-PLUG-TRUST-MW_04.07.xx.zip" available?

Or it could be different issue other than Applet version mismatch ?

One correction. I was wrong. Secure IC is SE052F2HN2 not SE050C2HQ1 .

Hi @daisuke2 ,

Please kindly refer to table 3 in https://www.nxp.com/docs/en/application-note/AN14028.pdf for details regarding the Cmake-settings for SE052F.

Hope that helps,

Have a great day,
Kan

Hi Kan,

I fixed the cmake flag SE05X_C and define SSS_PFSCP_ENABLE_SE052_B501=1 in header file.

But it still can't establish secure channel.

--------------------------------

I tried "DPTMW_SE05X_Auth=None". This did not work before, but

Is it possible to control SE052F2HN2 without scp3 secure channel?

Does this applet version mismatch mater at all?

Hi @daisuke2 ,

How did you change the default platformSCP keys for SE052F? It is not in the head file, it is in the fsl_sss_ftr.h.in file including options to select one of the predefined default
Platform SCP keys. This file is located in: simw-top/sss/inc.
Alternatively, you may set up a file to contain the default platformSCP keys for SE052F. Please refer to SE-PLUG-TRUST-MW_04.07.01/simw-top/doc/appendix/platfscp.html for more details.

PlatformSCP is mandatory for SE052F2 as required by FIPS certification.

Does this applet version mismatch mater at all? - I didn't find any mismatch info from the log. what are you referring to?

Have a great day,
Kan

Hi Kan,

Tried 10.11 Using own Platform SCP03 Keys.

Looks does not work either. somehow keep getting 'Unknown key type' error when i setup local key file.

Hi @daisuke2 ，

The following is the default platformSCP keys for SE052F, was it the same as yours? please kindly refer to https://www.nxp.com/docs/en/application-note/AN14277.pdf for more details.

Applet version mismatch info like "sss :INFO :Compiled for 0x70200. Got newer 0x70216" doesn't matter at all.

Have a great day,
Kan
