The explanation of "DER" should be droped in the section 2.
Because it is clear for KINK to use it because kerberos use it.

I also think the section 2 should be improved.  It is little verbose.
in particular, about Kerberos things, we should refer to the kerberos
specification.  so I suggest to write the following sentence into the
Introduction.

   It is assumed that the reader is familiar with the terms and concepts
   described in the Kerberos version 5.
