Host Identity Protocol Certificates
Abstract
The Certificate (CERT) parameter is a container for digital
certificates. It is used for carrying these certificates in Host
Identity Protocol (HIP) control packets. This document specifies the
certificate parameter and the error signaling in case of a failed
verification. Additionally, this document specifies the
representations of Host Identity Tags (HITs) in X.509 version 3 (v3).
The concrete use cases of certificates, including how certificates
are obtained and requested and which actions are taken upon
successful or failed verification, are specific to the scenario in
which the certificates are used. Hence, the definition of these
scenario-specific aspects is left to the documents that use the CERT
parameter.
This document updates RFC 7401 and obsoletes RFC 6253.

RFC 8002 HIP CERT October 2016
1. Introduction
Digital certificates bind pieces of information to a public key by
means of a digital signature and thus enable the holder of a private
key to generate cryptographically verifiable statements. The Host
Identity Protocol (HIP) [RFC7401] defines a new cryptographic
namespace based on asymmetric cryptography. The identity of each
host is derived from a public key, allowing hosts to digitally sign
data and issue certificates with their private key. This document
specifies the CERT parameter, which is used to transmit digital
certificates in HIP. It fills the placeholder specified in
Section 5.2 of [RFC7401] and thus updates [RFC7401].
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
RFC 2119 [RFC2119].
