3.3.2 Data origin authentication

Definition 3.3.2 Data origin authentication or message authentication techniques provide to one party which receives a message assurance of the identity of the party which originated the message. Often a message is provided to receiver along with additional information so that the

receiver can determine the identity of the entity who originated the message. This form

of authentication typically provides no guarantee of timeliness, but is useful in situations

where one of the parties is not active in the communication.
