What is Authenticated Encryption Authenticated encryption is a cryptographic technique that combines both data encryption and message authentication into a single operation. It ensures not only the confidentiality of data but also its integrity, effectively protecting against unauthorized access and tampering. By incorporating encryption and message authentication codes (MACs) together, authenticated encryption guarantees that not only is the information kept secret from unauthorized parties, but any modifications or alterations to the data can be detected, preventing malicious manipulation.
