Which of the following has a storage root key?

A.
HSM

B.
EFS

C.
TPM

D.
TKIP

Explanation:
Trusted Platform Module (TPM) is a hardware-based encryption solution that is embedded in the system’s
motherboard and is enabled or disable in BIOS. It helps with hash key generation and stores cryptographic
keys, passwords, or certificates on non-volatile (NV) memory. Data stored on NV memory is retained unaltered
when the device has no power. The storage root key is embedded in the TPM to protect TPM keys created by
applications, so that these keys cannot be used without the TPM.
