AES-XTS: Error "General exception. Contact service provider." #326

testSessionId 503716

vsId 2285478

Algorithm registration "revision":"2.0", "algorithm":"ACVP-AES-XTS", "direction":[ "encrypt", "decrypt" ], "keyLen":[ 256 ], "payloadLen":[ { "min":128, "max":65536, "increment":128 } ], "tweakMode":[ "number" ], "dataUnitLen":[ 64000 ], "dataUnitLenMatchesPayload":false

Expected behavior I expect the ACVP server to provide me with test cases. Instead, I receive an error "General exception. Contact service provider." The interesting thing is that when I delete my test vectors and request a fresh batch, the vector set that has this error is always for the same algorithm AES-XTS and no other vector sets have this error. I included the AES-XTS configuration above.

After retying to request test vectors many times, the error does go away and I get test cases, but the error happens frequently enough that this is a problem.

Hi @amr-atsec, if you update the dataUnitLen to include all supported payloadLens, does this error persist?

The error does not persist after updating the dataUnitLen to include all supported payloadLens. Thank you for your help.
