It's been a while since I have worked in this space but the underlying protocol (AIS) is incredibly lacking in terms of security due to the nature of plain text transmission & lack of authentication. I'm not sure if these issues have been addressed but below is some great research from 2014 on the matter [1][2].

The payload length for a single AIS slot is 168 bit. So there is really no room for any kind of security headers.
