Changes between -03 and -04 We updated the document based on the comments recieved during the IETF 109 WG meeting including Carsten, Russ, Stefan, Benjamin, Olle, Fraser, etc.
- unwrapped CBOR positive bignum (~biguint) used for serialnumber and validity - Use draft-ietf-cbor-tags-oid for OIDs, which are no longer called relative. - Fixed ambiguity with hex. Draft now only compresses EUI-64 with capital letters of the form "HH-HH-HH-HH-HH-HH-HH-HH" - Removed the single array in issuer optimization - Removed several extension optimization as a simplification. - Added "v3" in several places - Added id-at-organizationIdentifier - Added support of OtherName - Added a note that certificates can be identified with 'kid' by storing them in a dictionary. - Added reference to ietf-tls-certificate-compression - Editorial fixes Note that these changes does not increase the size of the constrained example certificate.

Name: draft-mattsson-cose-cbor-cert-compress Revision: 04 Title: CBOR Encoding of X.509 Certificates (CBOR Certificates) Document date: 2020-11-24 Group: Individual Submission Pages: 28 URL: https://www.ietf.org/archive/id/draft-mattsson-cose-cbor-cert-compress-04.txt Status: https://datatracker.ietf.org/doc/draft-mattsson-cose-cbor-cert-compress/ Htmlized: https://datatracker.ietf.org/doc/html/draft-mattsson-cose-cbor-cert-compress Htmlized: https://tools.ietf.org/html/draft-mattsson-cose-cbor-cert-compress-04 Diff: https://www.ietf.org/rfcdiff?url2=draft-mattsson-cose-cbor-cert-compress-04 Abstract: This document specifies a CBOR encoding of PKIX profiled X.509 Certificates. The resulting certificates are called "CBOR certificates". The CBOR encoding supports a large subset of RFC 5280, while at the same time producing very small sizes for certificates compatible with RFC 7925. The CBOR encoding can be used to compress DER encoded X.509 certificates and to encode natively signed certificates. When uses to compress DER encoded X.509 certificates, the CBOR encoding can in many cases compress RFC 7925 profiled certificates with over 50%. The document also specifies COSE headers for CBOR certificates as well as a TLS certificate type for CBOR certificates. 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.
