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.
