Hi,
IRTF Crypto Forum excellent work (just adopted from individual work)
on safety limits of key usage in AEAD algorithms. This will become
a primary reference in a number of new or updated RFCs across both
transport and application protocols.
Cheers,
- Ira

Title : Usage Limits on AEAD Algorithms
Authors : Felix Günther

Filename : draft-irtf-cfrg-aead-limits-00.txt
Pages : 13

Abstract:
An Authenticated Encryption with Associated Data (AEAD) algorithm
provides confidentiality and integrity. Excessive use of the same
key can give an attacker advantages in breaking these properties.
This document provides simple guidance for users of common AEAD
functions about how to limit the use of keys in order to bound the
advantage given to an attacker. It considers limits in both single-
and multi-user settings.
