Trusted Platform Module (TPM) technology is designed to provide hardware-based, security-related functions. A TPM chip is a secure crypto-processor that is designed to carry out cryptographic operations. The chip includes multiple physical security mechanisms to make it tamper-resistant, and malicious software is unable to tamper with the security functions of the TPM.
Some of the key advantages of using TPM technology are that you can:
- Generate, store, and limit the use of cryptographic keys.
- Use TPM technology for platform device authentication by using the TPM's unique RSA key, which is burned into itself.
- Help ensure platform integrity by taking and storing security measurements.
The most common TPM functions are used for system integrity measurements and for key creation and use.
