I also need to test CCM and GCM mode and realized that I cannot use the CLI for that. So, I started writing a program to do the tests (wanted to avoid this). The XTS works with the data from the one file, but I still do not understand how to make use of the "data unit sequence number" - anybody!? Also the KAT for the CCM has for example the following information:
[Alen = 0, Plen = 0, Nlen = 13, Tlen = 4] Key = 4bb3c4a4f893ad8c9bdc833c325d62b3 Count = 30 Nonce = 5a8aa485c316e9403aff859fbb Adata = 00 CT = 90156f3f Result = Pass Payload = 00 Can anybody please explain to me how I must use the parameters. For instance what is the plaintext? Reagrds, LJB
