I have a question regarding AN11910 (v1.5) on section 4.8.2 KeyNo to be changed equal AuthKey
In Table 11, step 15 (Cmd.ChangeKey C-APDU), the format of the data seems odd. There is no CLA,INS,P1,P2,Lc and Le. Shouln't it be like in Step 19 of Table 10? And the expected R-APDU is 00? I have reproduced the table steps below.
Table 10, Step 19
Cmd.ChangeKey C-APDU:
90 C4 0000 29 01
34B28FC4B47B414FA65FBC25018A0874E68F10B9F85C72DCB84B80C390B85E5D
F492468FEE79BC81
00
Table 11, Step 15
Cmd.ChangeKey C-APDU
C6 0000
E1B62916EDE2BD9E76615DE26733B843B554D0594A52ABAE7ACD218F4CBA6490
3747461D39B3B530
Also, is 3747461D39B3B530 this a CMAC generated from
Ksesauthcmac = E1F374D1F5DD913F0D3ACA52B149A4EA
Message = C6 0000 96780CB0 00
E1B62916EDE2BD9E76615DE26733B843B554D0594A52ABAE7ACD218F4CBA6490
where TI = 96780CB0, CmdCtr = 0000.
I tried but I could get the same result. Am I missing something here?
I have also verified my results online at this http://artjomb.github.io/cryptojs-extension/
