Edit WUSB Device or Host Connection Context using
WUSB Settings
For Certified WUSB, UWBTracer/Trainer can derive temporal keys (PTK) in real-time
from in-band WUSB Four-Way-Handshakes. UWBTracer/Trainer continuously monitors
the WUSB traffic and derives a new temporal key (PTK) whenever a new WUSB
Four-Way-Handshake process occurs. UWBTracer/Trainer can track
Four-Way-Handshakes for up to 32 different WUSB Connection Contexts.
Note: If you have multiple Four-Way-Handshakes for different pairs of devices,
make sure that the Host completes the Four-Way-Handshake process with
one device at a time.
To decrypt secured traffic using connection context, in the Device List dialog box,
program the WUSB Connection Context (CDID, CHID, CK) that exists between the
WUSB Host and a WUSB Device. UWBTracer/Trainer tracks the WUSB
Four-Way-Handshake between the Host and the Device and derives the PTK.
