Message authentication is a security measure used to verify the integrity and origin of a message by ensuring that it has not been altered and comes from a trusted source.
Message Authentication Definition: Message authentication is a security measure used to verify the integrity and origin of a message by ensuring that it has not been altered and comes from a trusted source.
Message Authentication ensures that a message has not been altered in transit and comes from the expected sender. This is typically achieved through cryptographic techniques like digital signatures or message authentication codes (MACs) to verify the integrity and authenticity of the message.
Message Authentication is one of the topics you'll master in the Security+ Boot Camp.
