The IPsec series of protocols makes use of various cryptographic
algorithms in order to provide security services. The Internet Key
Exchange (IKE) protocol is used to negotiate the IPsec Security
Association (IPsec SA) parameters, such as which algorithms should be
used. To ensure interoperability between different implementations,
it is necessary to specify a set of algorithm implementation
requirements and usage guidance to ensure that there is at least one
algorithm that all implementations support. This document updates RFC
7296 and obsoletes RFC 4307 in defining the current algorithm
implementation requirements and usage guidance for IKEv2, and does
minor cleaning up of the IKEv2 IANA registry. This document does not
update the algorithms used for packet encryption using IPsec
Encapsulating Security Payload (ESP).
This document is a product of the IP Security Maintenance and Extensions Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
