Advanced Topic 43 of 51 Security & Cryptography
Trusted Execution Environments
Hardware-isolated enclaves protecting code and data.
How it works
TEEs (Intel SGX, ARM TrustZone, AMD SEV) isolate code and data in hardware-protected enclaves with remote attestation proving what is running.
Where it is used
Confidential computing, DRM, key storage.
Common pitfall
Side-channel attacks have repeatedly affected TEEs.
Where it fits in the course
Trusted Execution Environments is topic 43 of 51 in Security & Cryptography, rated Advanced. It follows Sandboxing. The next topic is Reverse Engineering.
