How to preserve integrity of web-base transmission of information?
Of course, there are many things like PGP, SHS up to the task. But this idea is really about using simple tool to outwit the resourceful enemy.
Suppose we have a message M, the sender first checksum it(c). And checksum the message of checksum(cc), and the message along with the checksum(in front or back)(ccs). Now s/he first send a message contain both ccs and c with the reference of the time s/he is going to send the message, later s/he send another message contain M and cc with the reference of time the previous message is sent. I would bet 1 million if someone can intercept and alter the message without being noticed.
