Secure Element

Security

Secure Enclave Private Key Passkey Trusted Execution Environment (TEE)

Tamper-resistant hardware component for secure key storage and cryptographic operations.

Definition

A secure element is a tamper-resistant hardware module that stores cryptographic keys and can perform cryptographic operations internally, reducing exposure of private keys to the main OS.

In plain English Tamper-resistant hardware component for secure key storage and cryptographic operations.

Why this matters

Why it matters: Hardware-backed key protection improves security for authentication and encryption, reducing key theft and impersonation.

Example

Example: Use hardware-backed keys for passkeys and payment tokens; restrict key export and require user verification.
