Of the 200+ test vectors only 10 are semi-authentic. The ten are from the Simon and Speck paper but they had permutations applied to them so they worked with the algorithms described in the paper. The remaining 200 or so were generated with Crypto++ using straight C++ code. The library generated the test vectors because we don't have a reference implementation
We recently learned our Simon and Speck implementation was wrong. The removal will stop harm until we can loop back and fix the issue.
The issue is, the paper, the test vectors and the ref-impl do not align. Each produces slightly different result. We followed the test vectors but they turned out to be wrong for the ciphers.
We have one kernel test vector but we don't have a working implementation to observe it to fix our implementation. Ugh...
The tests were generated using Crypto++ and the straight C++ implementation. It should allow us to test the SSE and NEON impelmentations and multiple blocks
