Again, we are going into the weeds, and certainly beyond the intent of our licenses, and the regulating agencies. How do you know the identity of a ham on RF? When I make FM/SSB contact, I have NO means to authenticate the other parties - nor do they have a means to authenticate me. There is no rationale to apply authentication scrutiny to one mode of ham radio communications, yet, entirely ignore it on another.

There are various ways to accomplish this, many of which have been discussed on the list. For example, emails can be authenticated with a PGP digital signature. The equivalent layer 3 technology is IPsec(AH). Tom KD7LXL
