Advanced Message Authentication

Advanced Message Authentication involves secure techniques to verify that digital messages or data originate from a trusted source and haven't been altered during transmission. It uses cryptographic methods, such as digital signatures or Message Authentication Codes (MACs), to create unique identifiers tied to the message. If the message is tampered with or forged, the authentication process detects the change, ensuring data integrity and authenticity. This is essential for protecting sensitive information, maintaining trust in digital communications, and preventing fraud or unauthorized access.
