What hardware component is used to generate, store, and manage cryptographic keys?

A TPM, or trusted platform module, is a hardware-based, cryptographic processor that is used to generate, store, and manage cryptographic keys. It is also used to help ensure platform integrity by allowing boot validation processes to occur in a secure manner. A CPU is the main processor for a system, NSA is the National Security Agency, and a CCA is a chosen ciphertext attack, a type of attack against cryptographic systems where the attacker can cause a cryptographic system to encrypt known text for analysis.
