Hi Pablo,

We verified vectors mentioned in below link in our platform and all the vectors passed (i.e: the digest matches with the doc).
http://www.is.cas.cn/ztzl2016/zouchongzhi/201801/W020180126529970733243.pdf
The ZUC-256 Stream Cipher<http://www.is.cas.cn/ztzl2016/zouchongzhi/201801/W020180126529970733243.pdf>
The ZUC-256 Stream Cipher 5 3. X 2 = s 7L ks 5H 4. X 3 = s 2L ks 0H, where s iH is the high 16 bits of the cell s i and s jL is the low 16 bits of the cell s j. F(X 0;X 1;X 2) 1. W = (X 0 R 1) R 2 2. W 1 = R 1 X 1 3. W 2 = R 2 X 2 4. R 1 = S(L 1(W 1L kW 2H)) 5. R 2 = S(L 2(W 2L kW 1H)), where S = (S 0;S 1;S 0;S 1) is the 4 parallel S-boxes which are the same as those used in the previous ZUC ...

Could you please check if these vectors work in your platform.

Hi Pablo,

Verified with updated test vector.  the output did not change from previous output but also, it did not match the ouput present in the vector.

Regards
Sagar

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/<https://urldefense.proofpoint.com/v2/url?u=http-3A__patches.dpdk.org_project_dpdk_patch_20211031220421.52181-2D1-2Dpablo.de.lara.guarch-40intel.com_&d=DwMFAg&c=nKjWec2b6R0mOyPaz7xtfQ&r=9VCCg7VNdg-jfzaFw1fN59x7Py9yM-ofwvekNj6MPxM&m=2eElny5n4QewacnppQimeCdeyB6B6GXxfdF4oet4KAlTXpwgcfhUF0Z3q2Ph4evt&s=pputaMk4g9cVhsjiJ1euKMLuGx24bIVTDh0AA4WrKwI&e=>



Could you check if they work for you?



Thanks,

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,
