Simon Lemay and Hannes Tschofenig gave a tutorial about the Lightweight Machine-to-Machine (LWM2M) standard developed by the Open Mobile Alliance (OMA) to participants from the IETF ACE working group.
LWM2M offers several features that are relevant for Internet of Things security and also for the work in the IETF ACE working group, such as: Software Updates, Distribution of keys and access control policies (during a process called bootstrapping in the specification), Remote Device and Application, Configuration, and Diagnostics.
In summary, LWM2M is a device lifecycle management solution that builds on IETF protocols designed to be lightweight, such as CoAP, various CoAP extensions (such as Resource Directory), and DTLS.
The slide deck should give you an idea what we have been talking about.
