Message authentication
From Wikipedia, the free encyclopedia
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.[1] Message authentication does not necessarily include the property of non-repudiation.[2][3]
Message authentication is typically achieved by using message authentication codes (MACs), authenticated encryption (AE) or digital signatures.[2]
