Hi all, the firmware encryption draft has seen a lot of updates since the last IETF meeting. This is partially due to the WGLC issued by the chairs (see https://mailarchive.ietf.org/arch/msg/suit/8neAh2-H2cZ_Uzqs4FY1x9_42sM/) and the responses we have received afterwards. Thanks again to all reviewers. We submitted in total 5 (!) draft updates since July. As expected, the diff is fairly large and hard to read: https://author-tools.ietf.org/iddiff?url1=draft-ietf-suit-firmware-encryption-13&url2=draft-ietf-suit-firmware-encryption-18&difftype=--html In summary, we made the following changes: * The context information structure was changed based on the discussions at the San Francisco IETF meeting. This required updates to all examples (and consequently to the code). * More examples have been added, which now use AES-CTR and AES-CBC in Section 7 regarding the use of firmware updates on devices with flash memory. There are now also complete examples with ES-DH in addition to AES-KW. Big thanks to Ken for writing the AES-CTR/-CBC code to produce the examples! * Countless wording changes and editorial improvements. The document is getting very close to completion (from the WG point of view). I would like to request a presentation slot to discuss the remaining reviews/open issues (which can be found at https://github.com/suit-wg/suit-firmware-encryption/issues). Ciao Hannes
