Abstract
We show how to use a browser plug-in and a central Registrar server, to let users send registered or validated electronic messages in a lightweight manner, without using computationally expensive Public Key Infrastructure methods. To users, it is analogous to post office certified or registered mail. Our method can be done if the users, as senders and recipients, are at major ISPs, who have web pages for writing and reading messages, whose structure is known or can be found by the plug-in. Our method does not need the involvement of the ISPs, though that would facilitate some operations.
