RFC 8645: Re-keying Mechanisms for Symmetric Keys

In plain English — editorial summary, not part of the RFC

A certain maximum amount of data can be safely encrypted when encryption is performed under a single key. This amount is called the "key lifetime". This specification describes a variety of methods for increasing the lifetime of symmetric keys. It provides two types of re-keying mechanisms based on hash functions and block ciphers that can be used with modes of operations such as CTR, GCM, CBC, CFB, and OMAC. This document is a product of the Crypto Forum Research Group (CFRG) in the IRTF.
