Hi, We have submitted a new version of the CBOR certificate draft. https://tools.ietf.org/html/draft-raza-ace-cbor-certificates-04 The changes are: - The profiling section has been removed; the profiling now relies completely on RFC 7925. The aim is to be compatible with all RFC 7925 profiled certificates. - The encoding has been modified to increase compression and some missing pieces have been filled in. - Example DER encoded RFC 7925 certificate with corresponding CBOR encoding. The example certificate is compressed from 314 to 136 bytes, a compression rate of 57%. General purpose compression algorithms (without dictionary) seems not able to compress RFC 7925 profiles certificates. zlib compressed the example cert 9%, but other certificates and compression algorithms did in many cases increase the size. We have submitted two drafts that use draft-raza-ace-cbor-certificates to compress X.509 certificates in TLS 1.3 and COSE. https://tools.ietf.org/html/draft-mattsson-tls-cbor-cert-compress-00 https://tools.ietf.org/html/draft-mattsson-cose-cbor-cert-compress-00 Cheers, John -----Original Message----- From: "internet-drafts@ietf.org" <internet-drafts@ietf.org> Date: Monday, 9 March 2020 at 18:41 To: Joel Hoglund <joel.hoglund@ri.se>, Göran Selander <goran.selander@ericsson.com>, Martin Furuhed <martin.furuhed@nexusgroup.com>, John Mattsson <john.mattsson@ericsson.com>, Shahid Raza <shahid.raza@ri.se>, Joel Höglund <joel.hoglund@ri.se>, John Mattsson <john.mattsson@ericsson.com>, Göran Selander <goran.selander@ericsson.com> Subject: New Version Notification for draft-raza-ace-cbor-certificates-04.txt A new version of I-D, draft-raza-ace-cbor-certificates-04.txt has been successfully submitted by =?utf-8?q?John_Preu=C3=9F_Mattsson?= and posted to the IETF repository. Name: draft-raza-ace-cbor-certificates Revision: 04 Title: CBOR Profile of X.509 Certificates Document date: 2020-03-09 Group: Individual Submission Pages: 16 URL: https://www.ietf.org/internet-drafts/draft-raza-ace-cbor-certificates-04.txt Status: https://datatracker.ietf.org/doc/draft-raza-ace-cbor-certificates/ Htmlized: https://tools.ietf.org/html/draft-raza-ace-cbor-certificates-04 Htmlized: https://datatracker.ietf.org/doc/html/draft-raza-ace-cbor-certificates Diff: https://www.ietf.org/rfcdiff?url2=draft-raza-ace-cbor-certificates-04 Abstract: This document specifies a CBOR encoding and profiling of X.509 public key certificate suitable for Internet of Things (IoT) deployments. The full X.509 public key certificate format and commonly used ASN.1 DER encoding is overly verbose for constrained IoT environments. Profiling together with CBOR encoding reduces the certificate size significantly with associated known performance benefits. The CBOR certificates are compatible with the existing X.509 standard, enabling the use of profiled and compressed X.509 certificates without modifications in the existing X.509 standard. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
