Resending MT63 messages
- Butch's suggestion of resending formal messages in order to prove their
accuracy is commendable in intent, but ridiculous in concept. The waste of
time and bandwidth is quite unnecessary.
Let's say that a message was sent with a checksum attached - then all you
have to do to prove accuracy is to recompute and check the checksum, which
can be done WITHOUT retransmission, and independently by each receiver. It
can also be done off-line. All that needs happen is to send a request for
retransmission IF the message was wrong.
In addition, a simple mechanism such as this also provides the ability to
add authenticity checking and public key encryption. These features can be
provided by a separate application on top of MT63 or whatever the
transmission mechanism is.
