Security

Trusted Platform Module (TPM)

NOTE: For more information about the TPM, see https://developer.ubuntu.com/en/snappy/guides/security-whitepaper/.
TPM is only supported on devices that have TPM hardware installed on products with Snappy-enhanced security support. The TPM on/off setting is configurable in the BIOS and manageable in the operating system.

If TPM is turned off, the device node (/dev/tpm0) does not exist.

(plano)ubuntu@localhost:~$ ls /dev/tpm0
ls: cannot access /dev/tpm0: No such file or directory

If TPM is turned on, the device node (/dev/tpm0) exists.

(plano)ubuntu@localhost:~$ ls /dev/tpm0
/dev/tpm0
