Failures on ACVP Vectors for ML-DSA-65 and ML-DSA-87

[Dhruva21]

I have built liboqs-python wrapper module which internally uses liboqs library. I was able to try sample python scripts present in examples directory.

I wrote some sample script to test the ACVP vectors (signature verification) present in liboqs source code: https://github.com/open-quantum-safe/liboqs/tree/main/tests/ACVP_Vectors/ML-DSA-sigVer-FIPS204.
I see there are three failures for ML-DSA-65 and three failures for ML-DSA-87 as shown below.

Is there anything that needs to be updated from my side or there is some issue with test vectors I'm currently using?

Hi @Dhruva21, liboqs doesn't yet implement ML-DSA (final standard). See open-quantum-safe/liboqs#1919 which tracks the integration.

Appendix D.3: in the final version of ML-DSA, all of the bits of 𝑐 ̃ are used in the generation of 𝑐 (Algorithm 29),...

Hi @bhess , thank you.

If my understanding is correct, open-quantum-safe/liboqs#1919 --> this change is for tracking the integration of final implementation of ML-DSA (final standard) correct? Once all TODO's are done the code will be merged?

Reason for the above question is, I checked out to this branch bhe-fips204-final, still I see few ACVP vectors in ML-DSA-44, ML-DSA-65 and ML-DSA-87 are failing..

And can I know where can I find the vectors online or how to generate those?

Thanks,

Correct.

Yes, this is expected and related to the first two Todos in open-quantum-safe/liboqs#1919

And can I know where can I find the vectors online or how to generate those?
