Authenticated encryption

Authenticated encryption is a cryptographic technique that ensures both the confidentiality and authenticity of data. Authenticated encryption is crucial in preventing adversaries from intercepting and manipulating data, as it secures communication against both unauthorized access and tampering.

This method ensures that even if an adversary intercepts the data, they cannot decrypt it or alter its integrity without detection.

Implementing protocols such as the CCSDS SDLS, which incorporates encryption, authentication, and authenticated encryption is essential for protecting space-link communications.
