A basic principle of Project Daisho is that we want to monitor communication media at the physical layer or as close to the physical layer as we are able to achieve. Since any monitoring platform is capable of reconstructing activity at the monitored layer or higher, we think that security applications will be best served by monitoring at the lowest possible layer.
Dominic and I are joined on this project by Marshall Hecht, Jared Boone, Mike Kershaw, and Benjamin Vernoux. It is a big project, and we are thankful to have support from DARPA's Cyber Fast Track program.
The project is entirely open source hardware and software, and it has many potential applications beyond monitoring of communication systems. We're especially excited to be producing the world's first open source USB 3.0 device core for implementation of SuperSpeed USB with a transceiver IC and FPGA. (The USB 2.0 functions are already working!)
