Hi Sagar,

Thanks for flagging this. I submitted a patch fixing the IV of the test vectors I pushed (it didn't change the output):
http://patches.dpdk.org/project/dpdk/patch/20211031220421.52181-1-pablo.de.lara.guarch@intel.com/

Could you check if they work for you?

Thanks,
Pablo

Hi Pablo,

Tried the test vector zuc256_test_case_auth_1 and the digest did not match with the generated digest in our platform.

As per spec, IV[i] for i = 17 to\x14 24 are 6-bit string occupying the 6 least signi cant bits of a byte.
But in the vectors, The values in the IV(byte -17 to 24) are > 0x3f.

Could you please elaborate how these bytes are considered for generation of digest.

Regards
Sagar

The new vectors are failing for us. Could you check if the ones we added work for you?

Thanks,
