I can't wait for the same demo next year, but wireless. I wish I were joking:
The WiGig Bus Extension (WBE), which can enable a wireless
version of the PCI Express (PCIe) slots used to connect
everything from video cards to hard drives. WBE is now a
published specification available to members of the
consortium.
WiGig Bus Extension (WBE) aka PCIe over Wi-Fi, coming to a laptop near you.
- bravo22 12y agoThere is already a wireless USB. WBE would essentially replace the cable. It is invisible to upper stacks. There is encryption/scrambling. I'm sure there are vectors for snooping attacks but I don't see viable "imitation" attacks where you could issue commands on behalf of the other device.
- wigigpci 12y agoNo need to issue commands, just provide an Option ROM over Wi-Fi like this attack. It's the same PCI protocol after all, just over Wi-Fi...
- bravo22 12y agoPCIe is a bus. It is the drivers that would choose to read and execute option ROM. It isn't part of the protocol actually. If your peripheral device is compromised by a third party (say NSA) then it doesn't matter if it is over wireless or cable.
