SGX Machine Harware Key

[Sam5]

Hi,

Hardware keys are same for each SGX machine or are they are different per-machine? Mean that we can theoretically get the same key if we run the same enclave on different SGX machines?.

-Thanks

Hi Sam,

All keys are device independent. SGX Hardware keys are unique to the platform. Two different systems will not derive the same key from the same enclave. i.e., on different CPU the same enclave will get different keys using EGETKEY.
