Which term denotes the hardware standard designed for secure storage of encryption keys and identity information?

• A. Application Programming Interface (API)
• B. Trusted Platform Module (TPM)
• C. Escrow
• D. Data In Motion

Answer: (B)

Secure storage of encryption keys and identity information is provided by a dedicated hardware module called the Trusted Platform Module. The TPM is a secure cryptoprocessor that creates, stores, and uses cryptographic keys in a tamper-resistant environment, isolated from the main system. It acts as a hardware root of trust, helping ensure that keys are protected even if the operating system or applications are compromised. Features like secure boot and attestation rely on the TPM to verify platform integrity, and keys can be sealed to specific hardware and platform states so they only release under trusted conditions. This makes the TPM the hardware standard designed specifically for protecting keys and identity data. In contrast, an application programming interface is software-based and merely provides a way for software to request cryptographic services; escrow is about third-party custody of keys, not a hardware security module; data in motion refers to data being transmitted, not key storage.
