PQC Support on STM32U585 controller

[PJose.4]

Hi Everyone

Requesting clarification on one topic:

Does STM32U585 have support for PQC algorithm with any software library that has been validated on the same controller, as there is a requirement for PCI PTS 7, that the device should support PQC Algorithm and we need an evidence to show the same for the same controller. On searching XCube-PQC Library supported devices mentions STM32H563ZI only.

Requesting confirmation in this regard

Thanks and Regards
Philip

Hello @PJose.4 ,

new cryptolib supporting most of STM32 will be available in next 2 weeks.

If you use ML-DSA the current one should work on U5

Hello @Jocelyn RICARD 
Greetings

Thanks for your update

After checking the current release note for XCUBE_CRYPTOLIB(v4.6), i couldnt find ML_DSA as well, in this case i Should wait for the latest package to be released right? Attaching available packages for current cryptolib

Release note CRYPTOLIB

Thanks again for your support

Hello @Jocelyn RICARD,

Thank you for the information.

I am currently working on a project using STM32H753ZI (Cortex-M7), and I am facing a similar issue as the original poster regarding PQC library support.

May I ask whether STM32H7 / STM32H753 will be supported in the upcoming new cryptolib version you mentioned?

Thank you again for your support.

Best regards,
Nick

Hello,

I can confirm the new cryptolib V5 will support PQC : ML-KEM, ML-DSA, LMS and XMSS with examples for all targets supported in cryptolib V4

One important update: CRC dependency has been removed

Apparently there is still some delay, possibly 2 weeks more, for official delivery due to paper work (The libraries for each Cortex-M and examples are ready since one month ...)

Best regards

Thank you for the timely update @Jocelyn RICARD  -- this will be a very useful update to the cryptolib package.

Question -- do I remember this correctly -- the CRC thing was something "baked into" the library that looked for the CRC peripheral hardware to ensure the library was running on an STM32 (if you can say).  I never ran into problems but then again all my work is on STM32 anyway...

Cheers and thanks again.

Hi @Doug Barnes ,

yes, CRC purpose was to ensure cryptolib was running on STM32.

This means that on V5, ST cryptolib is able to run on any Cortex-M supported. I have not tested through :)

Best regards
