Therefore, this mode is not recommended as it will not provide the key benefits of full disk encryption. This is transparent to the user and will allow other users onto the hard drive. TPM-Only – Only the TPM is used to validate the boot files, operating system, and encrypted volumes. Read more Navigate DownīitLocker with TPM may be used for full disk encryption with the following modes: ■ In addition to boot integrity, TPM is also commonly associated with some implementations of full disk encryption.
By operating at the hardware level, the TPM chip can help ensure that kernel-mode rootkits are less likely to be able to undermine operating system security. The most commonly referenced use case for the TPM chip is ensuring boot integrity. Security functions can leverage the TPM for random number generation the use of symmetric, asymmetric, and hashing algorithms and secure storage of cryptographic keys and message digests. The TPM chip allows for hardware-based cryptographic operations. If included, a TPM chip is typically found on a system’s motherboard. Not all computer manufacturers employ TPM chips, but the adoption has steadily increased.
Joshua Feldman, in Eleventh Hour CISSP® (Third Edition), 2017 Trusted Platform ModuleĪ trusted platform module (TPM) chip is a processor that can provide additional security capabilities at the hardware level.
