Secure Enclave Architecture

Secure Enclave Architecture refers to the design of a dedicated subsystem within a processor that operates independently of the main OS to perform sensitive tasks. This architecture ensures that even if the kernel or application layer is compromised, the data within the enclave remains encrypted and inaccessible.

It is widely used in modern mobile devices to secure biometric data, payment credentials, and cryptographic keys. By providing a trusted path for input and output, it ensures that sensitive information is never exposed to the broader system memory.

This architecture is fundamental to building secure applications on potentially insecure hardware platforms. It creates a small, verifiable trust boundary within a complex and vulnerable system.
