!!! Overview
[{$pagename}] (or Data origin authentication) techniques provide to one party which receives a message assurance (through corroborative [evidence]) of the identity of the party which originated the message.
[{$pagename}] is most visible as using [Message Authentication Code]
!! Example Why [{$pagename}] is needed
Example (need for data origin authentication) A sends to B an electronic mail message (e-mail). The message may travel through various network communications systems and be stored for B to retrieve at some later time. A and B are usually not in direct communication.
B would like some means to verify that the message received and purportedly created by A did indeed originate from A.
Data origin authentication implicitly provides data integrity since, if the message was modified during transmission, A would no longer be the originator.
