Demoed the Signposts DNSSEC system at SIGCOMM. Working with Amir Chaudhry, Charalampos Rotsos, Richard Mortier, and others, we presented a system providing secure, simple communication channels between personal devices in a world dominated by NATs and middleboxes. Signposts uses DNSSEC-based naming to establish secure end-points while clients dynamically discover routes to overcome network obstacles. The demo showed devices on different networks behind various middleboxes seamlessly interconnecting to share data, with the system automatically adapting as network configurations changed.
