External Authentication security level (SCP03) and the expected data for them

I am trying to do External authentication on SMART CARD, using SCP03. The value of P1 is the security level that we are using for the authentication. May I know the possible values of the security levels and the data I need to pass for them?

If i understand your question correctly, there are three security level for command apdu:

  1. none: nothing is secure
  2. mac: command is clear but mac of command is calculated and added to the command
  3. enc: command is encrypted and mac of command added to thecommand

there are another two option for response security:

  1. rmac: like mac for response apdu
  2. renc: like enc for response apdu

I suggest you to study Globalplatform specification: https://www.globalplatform.org/specificationscard.asp
