What is TPM and How to Use It in Linux
What is TPM?
TPM (Trusted Platform Module) is a piece of hardware, usually found on your motherboard, that can perform cryptographic operations. It is designed to provide a secure way to store encryption keys and other sensitive information.
TPM 1.2 and TPM 2.0
There are two main implementations of TPM: TPM 1.2 and TPM 2.0. TPM 1.2 is the older version, and it is less secure than TPM 2.0. TPM 2.0 is the newer version, and it offers a number of security improvements over TPM 1.2.
In order to properly use TPM 2.0 devices in Linux, you will need the TPM2 software stack. This software stack provides the necessary drivers and libraries to support TPM 2.0 devices.
How to Use TPM in Linux
To use TPM in Linux, you will need to do the following:
- Enable TPM in your BIOS
- Install the TPM2 software stack
- Initialize the TPM
- Create a key using the TPM
- Use the key to encrypt data
Once you have completed these steps, you will be able to use TPM to protect your data from unauthorized access.
