test vectors for CTR DRBG
Hello, I'm looking for the test vectors for CTR DRBG random number generator. I got test vectors from http://csrc.nist.gov/groups/STM/cavp/documents/drbg/drbgtestvectors.zip which contains CTR_DRBG.rsp file. However, I'm looking for the following scenario which is not covered right now: [AES-128 no df] [PredictionResistance = False] [EntropyInputLen = 256] [NonceLen = 0] [PersonalizationStringLen = 0] [AdditionalInputLen = 0] Can anybody please provide such testing vectors? Thanks a lot! Jiri

So even though this scenario provides a nonce value, it is never used. Trust me I tested it myself ! (you can also verify in SP800-90 that no nonce is used when no df..) Cheers !

Hi Julien, thanks for the hint, I'm going to try it! Sorry for the long delay in response, I was quite sometime off-line and now I'm going through all the e-mails... Thanks!
