Properties of AEAD Algorithms
draft-irtf-cfrg-aead-properties-08

Technical Summary

Authenticated Encryption with Associated Data (AEAD) algorithms
provide both confidentiality and integrity of data.  The widespread
use of AEAD algorithms in various applications has led to an
increased demand for AEAD algorithms with additional properties,
driving research in the field.  This document provides definitions
for the most common of those properties, aiming to improve
consistency in the terminology used in documentation.

This document is a product of the Crypto Forum Research Group.


Research Group Summary

The first version of this document adopted by CFRG was posted on 21 December 2022
after a successful presentation at a preceeding CFRG meeting at IETF 115.
Update to the document were presented at several CFRG meetings since.
The document received interest in CFRG, but discussions weren't particularly
controversial.

Crypto Review Panel review was solicited in February 2024. The review
was provided by Russ Housley. Comments from that review were addressed in -04.

RGLC was initiated on 5 March 2024. Some feedback was received and several
issues were addressed/clarified in subsequent versions.


Document Quality

This document describes different cryptographic and implementation
properties of AEADs and it lists example of different AEADs satisfying
various listed properties.

The editor of the document has confirmed that he is not aware of
any IPRs related to the document.
