Motherboards with TPM connector

TPM

— TPM (Trusted Platform Module) allows you to encrypt the data stored on your computer using unique key that is practically unbreakable (it is extremely difficult to do this). The keys are stored in the module itself and are not accessible from the outside, and data can be protected in such way that their normal decryption is possible only on the same computer where they were encrypted (and with the same software). Thus, if information is illegally copied, an attacker will not be able to access it, even if the original TPM module with encryption keys is stolen: TPM will recognize the system change and will not allow decryption.

Technically, encryption modules can be built directly into motherboards, but it is still more justified to make them separate devices: it is more convenient for the user to purchase TPM if necessary, and not overpay for an initially built-in function that may not be needed.
