Cryptographic functions for encryption, decryption, signing, and verification. Platform configuration registers that record the boot process state.
TPM Encryption and Secure Identity Management
FileVault on Apple Silicon Macs utilizes the built-in Secure Enclave, a TPM-like processor. The module can seal data to specific configurations, ensuring that a encrypted volume or credential can only be unlocked when the firmware, bootloader, and critical system files match the expected hash values.
TPM encryption leverages a dedicated secure processor to safeguard the cryptographic keys that protect your most sensitive data. This process, known as sealing, means that even if a drive is moved to another device, the data remains inaccessible without the exact original hardware context.
TPM Encryption for Secure Identity Management
macOS uses the T2 security chip, a form of TPM, to manage FileVault keys and ensure the integrity of the startup process. During startup, the TPM compares these measurements to stored values.
