 Cryptographic Algorithm Implementation Requirements and Usage Guidance
for Encapsulating Security Payload (ESP) and Authentication Header (AH)
                    draft-ietf-ipsecme-rfc7321bis-00

Abstract

   This document updates the Cryptographic Algorithm Implementation
   Requirements for ESP and AH.  The goal of these document is to enable
   ESP and AH to benefit from cryptography that is up to date while
   making IPsec interoperable.

   This document obsoletes RFC 7321 on the cryptographic recommendations
   only.

1.  Introduction

   The Encapsulating Security Payload (ESP) [RFC4303] and the
   Authentication Header (AH) [RFC4302] are the mechanisms for applying
   cryptographic protection to data being sent over an IPsec Security
   Association (SA) [RFC4301].

   This document provides guidance and recommendations so that ESP and
   AH can be used with a cryptographic algorithms that are up to date.
   The challenge of such document is to make sure that over the time
   IPsec implementations can use secure and up-to-date cryptographic
   algorithms while keeping IPsec interoperable.

1.1.  Updating Algorithm Implementation Requirements and Usage Guidance

   The field of cryptography evolves continuously.  New stronger
   algorithms appear and existing algorithms are found to be less secure
   then originally thought.  Therefore, algorithm implementation
