At the IETF99 Hackathon, we plan to do some work on using COSE in the network.  See below.

# COSE in the network: Secure Wake-on-Radio (SWORN)

## Champions

* Olaf Bergmann
* Benjamin Piepiora

## Background

COSE is the CBOR object signing and encryption specification, RFC 8152-to-be.

COSE is mostly thought as a component for application protocols, but
it can be used in the network as well.

Wake-on-Radio can save a lot of power for battery-operated devices by
having them wake up and consume power only when there is actually
something to do.  But Wake-on-Radio provides a too easy DoS vector for
a battery depletion attack.  Secure Wake-on-Radio Nudging (SWORN)
enables a last-hop router to find out if the correspondent node was
authorized to wake up the device with a packet.

## Project

* Implement SWORN in an actual IoT scenario with Wake-on-Radio
* Demonstrate the power savings achievable
* Demonstrate the workflow for getting a correspondent node authorized
* Cooperate with other COSE connoisseurs and IoT power savers

* Specification: <https://tools.ietf.org/html/draft-bormann-t2trg-sworn>
