Internet Engineering Task Force (IETF) T. Heer Request for Comments: 8002 Albstadt-Sigmaringen University Obsoletes: 6253 S. Varjonen Updates: 7401 University of Helsinki Category: Standards Track October 2016 ISSN: 2070-1721 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. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 7841.

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]. 2. CERT Parameter The CERT parameter is a container for certain types of digitalShow full document text
