| Post subject: | Yubikey OTP function and TrueCrypt |
With a quick search I found a thread about TrueCrypt and I believe static passwords but I'm not particularly fond of them so I wonder if there's a way to integrate something that makes the key work with TrueCrypt (like smartcards or token) that utilize that server authentication so OTP works? |

It is challenging for many reasons. If you use the OTP functionality then the shared secret would have to be stored outside the encrypted drive, which defeats the purpose. Using the challenge/response mode of the yubikey would be preferable, but the tiny truecrypt boot loader does not provide any mechanism for extensibility, especially USB device support. These problems need to be solved for the good of the community. My company is working with Yubico to figure out how to do strong security with Truecrypt, because our product (AuthLite) would be more useful on a workstation if the drive was secure from offline attacks. |
