         BGPsec Algorithms, Key Formats, and Signature Formats

Abstract

   This document specifies the algorithms, algorithm parameters,
   asymmetric key formats, asymmetric key sizes, and signature formats
   used in BGPsec (Border Gateway Protocol Security).  This document
   updates RFC 7935 ("The Profile for Algorithms and Key Sizes for Use
   in the Resource Public Key Infrastructure").

   This document also includes example BGPsec UPDATE messages as well as
   the private keys used to generate the messages and the certificates
   necessary to validate those signatures.

RFC 8208          BGPsec Algs, Key & Signature Formats    September 2017

1.  Introduction

   This document specifies the following:

   o  the digital signature algorithm and parameters,

   o  the hash algorithm and parameters,

   o  the public and private key formats, and

   o  the signature formats

   used by Resource Public Key Infrastructure (RPKI) Certification
   Authorities (CAs) and BGPsec (Border Gateway Protocol Security)
   speakers (i.e., routers).  CAs use these algorithms when processing
   requests for BGPsec Router Certificates [RFC8209].  Examples of when
   BGPsec routers use these algorithms include requesting BGPsec
   certificates [RFC8209], signing BGPsec UPDATE messages [RFC8205], and
   verifying signatures on BGPsec UPDATE messages [RFC8205].
