Suppose I receive data from Bob and he says the data are generated or calculated by TEE (e.g., Intel SGX).
Is there any method, TEE, or auxiliary information like zero-knowledge in cryptography that he can provide to prove the data are indeed from TEE, not from an ordinary PC?
Then, everyone trust him the data are generated or calculated by TEE.
BTW, could you provide some materials or useful tutorials to learn SGX programming that is easy to understand?
