For a mobile device, such as a laptop, lots of people other than the device owner will have physical access.
The useful use-case of a TPM to me is the ability to encrypt my disk without having to type a decryption password each time I use it.
- freeone3000 2y agoIt does require someone to steal the entire laptop rather than just the hard drive, but… I don’t think that this was an actual worry, and the security result of encrypting to a device with the key stored in the same device is much like not encrypting.
- clhodapp 2y agoIt also makes it a lot harder to bypass the login screen, even if someone takes the whole laptop. In case you weren't aware, the ability to do a passwordless unseal can be tied to not tampering with the bootchain. It's not entirely bulletproof, but it's beyond the abilities of most thieves to bypass this (versus just popping the drive in another machine).
