🗝️Secure Enclaves

A quick overview explaining the concept of Secure Enclaves

A Secure Enclave is a protected area within a CPU that ensures the confidentiality and integrity of the code and data processed within it. Secure Enclaves address the challenging issue of providing secure execution for highly sensitive data.

Here’s how they achieve this:

• Secrecy of Cryptographic Key Material: Secure Enclaves keep cryptographic keys confidential.

• Transaction Privacy: They prevent any unauthorized access or spying on transactions, including by the owner or operator.

• Encrypted Data Search: They enable searching through encrypted, sensitive data.

• Cryptographic Signing: Secure Enclaves can sign data with cryptographic keys.

• Private Code Execution: They ensure that code runs with complete privacy.

• Code Attestation: They provide guarantees that the code running is exactly what it is supposed to be.

These capabilities solve a set of problems that other methods, like zero-knowledge proofs and homomorphic encryption, cannot fully address. Secure Enclaves offer a practical and elegant solution to securing sensitive data and execution processes.
