This demo presents Signposts, a system to provide users
with a secure, simple mechanism to establish and main-
tain communication channels between their personal cloud
of named devices. Signpost names exist in the DNSSEC hi-
erarchy, and resolve to secure end-points when accessed by
existing DNS clients. Signpost clients intercept user connec-
tion intentions while adding privacy and multipath support.
Signpost servers co-ordinate clients to dynamically discover
routes and overcome the middleboxes that pervade modern
edge networks. The demo will show a simple scenario where
an individual's personal devices (phone, laptop) are inter-
connected via Signposts while sitting on dierent networks
behind various middleboxes. As a result they will be able to
fetch and push data between each other, demonstrated by,
e.g., simple web browsing, even as the network conguration
changes.
