Update of BSI TR-03105 Part 3.2 available (V1.4.1)

The German BSI and French AFNOR have released an update with minor clarifications of their technical guideline BSI TR-03105 Part 3.2 focusing on conformity tests for ePassports implementing protocols like PACE and SAC (EACv1).

The new version 1.4.1of TR-03105 Part 3.2 includes changes in the following test cases:

  • ISO7816_II_2: The missing profile ‘ECDH’ is added to the profile of this test case according to the corresponding test case ISO7816_I_2 in test suite I.
  • ISO7816_II_3: There is a new test step added (step 3) to perform the additional command GENERAL AUTHENTICATE to perform key agreement correctly.
  • ISO7816_K_19: There are several meanings how to handle the ‘presence’ of a data group. A simple command SELECT to detect a data group of the chip is insufficient and may cause problems. In this test case the presence of data group EF.DG15 should be used as an indicator to perform Active Authentication. In the new version of this test case the wording is adapted to TR-03110 and is changed from “is present” to “if available”. On this way the discussion is moved from TR-03105 to TR-03110. From my point of view it makes sense to check if the relevant data group is listed in file EF.SOD. The information in EF.COM is note secured by Passive Authentication and may be corrupted. Instead of that, EF.SOD is secure and can be used as an indicator of the existence of a file on the chip.
  • ISO7816_L_13: In step 9 of this test case the command MUTUAL AUTHENTICATE is performed. In the old version of the specification this command was not complete. The missing Le byte is now added, so the command expects now 40 bytes (or 28 in hex) as response.
  • ISO7816_L_14: In the previous version of TR-03105 in step 8 of this test case a SELECT MF with parameter P2 = ‘0C’ is performed. ISO7816-4 specifies for bytes b4=1 and b3 =1 that no response data is expected if Le field is absent. This command causes problems on some COS implementations and so the command is replaced by a SELECT with P2 = ’00’ and Le = ’00’.

In the past I have missed such a list for every new released version of test specifications, like BSI TR-03105 or ICAO technical reports. So I hope, this list of modified test cases is helpful for your work in context of ePassport testing. If you are interested, please leave a comment and I will update this list with every new version of test specifications in context of smart cards used in ePassports and ID cards.
