In [[information security]], '''message authentication''' or '''data origin authentication''' is a property that a message has not been modified while in transit ([[data integrity]]) and that the receiving party can verify the source of the message. Message authentication does ''not'' necessarily include the property of [[non-repudiation]].

Message authentication is typically achieved by using [[message authentication code]]s (MACs), [[authenticated encryption]] (AE) or [[digital signature]]s.
Some cryptographers have researched [[subliminal channel]] systems that send messages that appear to use a "message authentication without secrecy" system, but in fact also transmit a secret message.
