Data origin authentication
Also known as message authentication, data origin authentication is an assurance that the source of the information is indeed verified. Data origin authentication guarantees data integrity because if a source is corroborated, then the data must not have been altered. Various methods, such as Message Authentication Codes (MACs) and digital signatures are most commonly used. These terms will be explained in detail later in the chapter.
