The updated Simon and Speck were re-added last night. The updated ciphers conform to the paper's specification and the kernel's implementation. The updated Simon and Speck will fail to arrive at the test vector answers published in the Simon and Speck paper. We hope the Simon and Speck team will publish updated test vectors one day so we can establish provenance for our test vectors.
