Re-keying Mechanisms for Symmetric Keys
RFC 8645

Received changes through RFC Editor sync (created alias RFC 8645, changed abstract to '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.
