Hardening and Speeding Up Zero-interaction Pairing and Authentication. (arXiv:2306.04458v1 [cs.CR])

Establishing and maintaining secure communications in the Internet of Things
(IoT) is vital to protect smart devices. Zero-interaction pairing (ZIP) and
zero-interaction authentication (ZIA) enable IoT devices to establish and
maintain secure communications without user interaction by utilizing devices'
ambient context, e.g., audio. For autonomous operation, ZIP and ZIA require the
context to have enough entropy to resist attacks and complete in a timely
manner. Despite the low-entropy context being the norm, like inside an
unoccupied room, the research community …
