AEAD
Abbreviation for Authenticated Encryption with Associated Data
In short and in plain language
AEAD is a way to encrypt data.
It keeps the data secret. At the same time, it checks that the data has not been changed.
Modern secure web links use such methods. So it shows up when someone changes data on the way.
Definition
AEAD designates encryption methods that not only keep data confidential but also check its integrity. Modern TLS connections use such methods in their cipher suites. Tampering with transmitted data can be detected this way.
