Chairs reminded participants of the NOTE WELL.

Brendan talked about a few manifest-related lessons from the Hackathon.  See slides.

- Attestations need to be defined, but they should be done in the RATS WG
- To assist with EdDSA and some post-quantum signatures, the signed portion of manifest payload will be an algorithm identifier and a hash value of the manifest contents
- Seems to be a need for a minimal loop operation

Emmanuel Baccelli talked about the Hackaton experience for the RIOT team.  See slides.

David Brown talked adding support for the SUIT manifest to MCUboot.  See info here: https://github.com/siot-hackathon/siot-hackathon.github.io/wiki/SUIT-and-MCUboot

Yuichi Takita talked about adding support for the SUIT manifest to a trusted execution environment.  See info here: https://github.com/siot-hackathon/siot-hackathon.github.io/wiki/SUIT-parser-running-on-OP%E2%80%90TEE

- A pseudo-TA was used, so the untrusted code and the trusted application code are delivered as one bundle

Emmanuel Baccelli (on behalf of Aydogan Ersoz) talked about the SUIT Integrate t_cose to RIOT OS.  See info here: https://github.com/siot-hackathon/siot-hackathon.github.io/wiki/SUIT---Integrate-t_cose-to-RIOT-OS

12  people plan to attend the IETF 107 Hackathon, and 4 plan to be at the SUIT table.
