The field of confidential computing is still in its infancy, to the pointwhere it lacks a clear, agreed, and established problem description. ElenaReshetova and Andi Kleen from Intel recently started the conversation by sharing their view of a potential threatmodel in the form of thisdocument, which is specific to the Intel Trust Domain Extension (TDX)on Linux, but which is intended to be applicable to otherconfidential-computing solutions as well. The resulting conversationshowed that there is some ground to be covered to achieve a consensus onthe model in the community.
