Hi, We got an action last meeting to propose new text for the charter. Please find a proposal below.
OLD is the charter *after* incorporating the changes proposed by John (as discussed in the meeting): https://mailarchive.ietf.org/arch/msg/cose/bUSlA5k5k855lVEq6ZnP1KPO0Cg/ NEW is the proposal. The first and last paragraph of OLD are unchanged, and the middle paragraph is replaced with two new ones. OLD --- A CBOR encoding of the compressed certificate profile defined in RFC 7925. It is expected that the compression works with a large subset of RFC 7925 and takes into consideration any updates in draft-ietf-uta-tls13-iot-profile-00. The compression may also include other important IoT certificate profiles like IEEE 802.1AR. It should be noted that this is not a new certificate architecture, rather it is a method of compressing current X.509 certificates that meet a specific profile into a smaller format. The compression algorithm is loss-less so they can be expanded and normal X.509 certificate processing used. This work will be based on draft-mattsson-cose-cbor-cert-compress. The working group will collaborate and coordinate with other IETF WGs such as TLS, UTA, LAKE to understand and validate the requirements and solution. --- NEW --- A CBOR encoding of the compressed certificate profile defined in RFC 7925. It is expected that the compression works with a large subset of RFC 7925 and takes into consideration any updates in draft-ietf-uta-tls13-iot-profile-00. The compression may also include other important IoT certificate profiles like IEEE 802.1AR. The main objective is to define a method of compressing current X.509 certificates that meet a specific profile into a smaller format. This compression algorithm is loss-less so they can be expanded and normal X.509 certificate processing used. Another objective is to explore the possibility to parse and verify the compressed X.509 encoding directly on the target device. This removes the need for compression, decompression, and DER parsing, with associated overhead and code, which is relevant for embedded implementations. This work will be based on draft-mattsson-cose-cbor-cert-compress. The working group will collaborate and coordinate with other IETF WGs such as TLS, UTA, LAKE to understand and validate the requirements and solution. --- Göran On 2020-09-23, 18:35, "COSE on behalf of John Mattsson" <[email protected] on behalf of [email protected]> wrote: Three suggestion regarding certificate compression in the charter. OLD "A CBOR encoding of the compressed certificate profile defined in RFC 7925." NEW "A CBOR encoding of the compressed certificate profile defined in RFC 7925.

The compression may also include other important IoT certificate profiles like IEEE 802.11AR." OLD: "This work will be based on draft-mattsson-cose-cbor-cert-compress and draft-raza-ace-cbor-certificates. It is expected these documents are to be combined into a single document."
