Oberon Security Drivers for nRF54L15

[grantrudd]

Hello,

Does the nrf_oberon library support the nRF54L series parts? In the technical documentation, it appears that M33 parts are supported:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/libraries/security/nrf_security/doc/drivers.html#nrf-oberon-driver

I am able to build my code (SDK/Toolchain version 2.9.0) for nRF52840 successfully using the nrf_oberon libraries, but the build fails for nRF54L15 targets with this error:

fatal error: ocrypto_aes_eax.h: No such file or directory
2 | #include <ocrypto_aes_eax.h>

If nrf_oberon does support the full range of M33 parts, are there any additional KConfigs necessary for the L15?

Thanks!

Hi Grant,

Could you let me know which operations are you doing using the oberon libraries.. It would be really helpful to verify the performance when using PSA API's with CRACEN. Are you doing  AES-ECB.?
As for the advantages: HW crypto provides more security, Resistance to physical attacks, less side-channel leakage, better performance on some/most workloads.

Regards,

Swathy

Yes, I opened a private ticket to discuss this further.
