    The advantage of SD cards is that in a pinch, the manufacturer can always ship a SD card to the customer (especially if the item is a more expensive appliance like a CNC mill.) As for a SD card reader, those are not too difficult to find (most modern laptops except MacBook Air models tend to have them built in.)

    I do agree that a USB flash drive would be better, but a SD card reader is fairly static. One knows that it will have the same device ID (in Linux) or drive letter (in Windows) no matter what, while one can attach a hub and all sorts of devices to a USB port, trying to exploit any possible faults in the USB controller or the OS wondering why it is seeing another keyboard when it is expecting a drive.

    SD cards are not perfect, but for a relatively high-value device, they are decent. If a device manufacturer is worried about physical attack, they could always ship SD cards using the built in signing/encryption (CPRM) and secure area to ensure that the ROM on the card hasn't been tampered with.

    Of course, for something uber cheap where the only thing that matters is price, one can just have the device be a USB destination, and just allow the user to copy the updated firmware via PTP or MTP to a space on the device, then power cycle. However, this assumes the device is small and portable.

    With a SD card and signed firmware, it definitely isn't 100%, but it will keep most attacks at bay. If more security is needed, the manufacturer can ship update SD cards out using the copy-protected region so the data on the card can't be tampered with, and it would provide another security layer against even physical tampering.

    The problem is that bugtastic firmware is just a sign to the "good enough" race to the bottom that plagues a lot of industries.

    Secure firmware upgrades are not rocket science. If a device doesn't have to be connected to the Internet [1], a SD card [2], a routine for signing firmware, and having an atomic transaction based upgrade process (so the upgrade either 100% completes or gets rolled back... no in between states) will solve this. Of course, some way to revert or roll back would be useful. Perhaps a "version 1.0" firmware burned into a ROM as an absolute failsafe.

    For Internet connected devices, a mechanism similar to above coupled with SSL/TLS and a failsafe way of checking hosts for updates. Since this is a separate mechanism from Web browsing, the SSL/TLS certs can be signed with a non-standard CA (although I'd not self-sign them just in case the cert got compromised on the server.) Then, it can basically do a wget on the firmware image, then pass it on to another mechanism for checking the signature and flashing the new firmware.

    1: Two Thunderbolt connectors on a port replicator or docking station. These would work for video out, as well as provide 8 (in TB 1) or 16 (in the TB 2 spec) PCI lanes. I wonder if this would be enough for an external video adapter.

    2: USB 3.1 with a type C connector. This is small enough to be on the device itself and support high amperage charging (as well as voltage higher than 5 volts if negotiated through the plug.)

    If one had to have cellular access, 3G chips are cheap, and passwords are relatively small. This would provide for backups (each device would have its own private key, so that when one wanted to access the cloud-stored backup with a new device, and old one would have to unlock and re-encrypt the backup, adding the new device's key.) It would also provide for remote erase capabilities [1].

    Biometrics are useful, but what about just going with a tried and true PIV/CAC token?

    I have always used authentication tokens. (Preferably, multiple tokens for redundancy.) For example, I have several Aladdin eTokens. They are set with a fairly short (16 character) user passphrase, and an obnoxiously long (but memorable) admin passphrase. Both passphrases will permanently lock if more than a certain number of bad attempts are done.

    These days, I wish there were a way to make an application that runs on a SIM card, similar to the ISIS e-Wallet system [1]. That way, decryption of keys could be done on the SIM (with the app having its own PIN/password), and it would have the same security as my old eTokens, except without the hassle of trying to find the PKCS#11 drivers.

    This would also allow for client certificates. They are unwieldy because they have to be copied to where one is browsing... but they take care of the authentication problem with ease. An intruder who hacks a Web server will get a list of certificates in use... which might show who may be using the server, but for any other use, would be worthless.

    If DARPA wants better password authentication, there can be two things done. One, we have a quite open mechanism in place -- TKIP, which is used by the Google Authenticator, Amazon, and many other places. The second would be DARPA/DoD to agree on some type of PIV/CAC spec, perhaps having a way to have cards be read by USB ports without a dedicated reader, or somehow get more vendors (Apple specifically) to embed a smartcard reader in their computers. Then, sell the smartcards.

    Done right, this would make life fairly easy, since a user just puts their card in a reader, types their PIN (perhaps it gets typed in on a different keyboard, or a light comes on the normal keyboard showing that the BIOS is reading it, nothing else.) Then from there, authentication almost anywhere is automatic, or a dialog pops up confirming/denying use of the key.
