| 1. Confidentiality of attestation/identity key: the TEE's private key(s) should never be accessible from outside the TEE and any operations involving them must be performed obliviously (independently of the key) to avoid leaking bits of the key via side channels. | ||
| 3. Integrity of computation: any TEE assets leaving the TEE, e.g. to DRAM, must be integrity checked by the TEE upon return. This includes the initial inputs and final output of the computation over its communication channel with the computation owner. | ||
| 4. Confidentiality of computation and its inputs/outputs: guaranteed based on confidentiality of the key(s) associated with the communication channel and resistance to side channel leakage (see 1.9 on TEE operators) | ||
| 5. Authenticity of the computation: guaranteed based on confidentiality of the attestation/identity key. | ||

There was a problem hiding this comment.
For other editors: time to renumber? Or maybe we just drop numbers entirely. This is where the limitations of the format stand out.
(Note that the "TEE Manufacturers" section includes subsection 1.9.1.

Adding a threat model section for the TEE itself.
Should it have references?
Also see #32 which adds the TEE operator and #34 which adds the TEE manufacturer.
