Recent months have seen an awakening of several large use cases of TEEs, from OpenAI calling for new and improved TEEs and Apple announcing a hardware-based private cloud, to Ethereum transactions being privately processed in TDX and other blockchains leveraging SGX for integrity. Having worked quite closely with several use cases that are at the center of this excitement, we are aware of both the promise which secure hardware holds, and of the current insufficiency of today’s hardware to service these use cases. TEE solutions currently on the market simply do not offer sufficient security guarantees while alternative secure hardware families like TPMs, secure elements and smart cards offer better (although not perfect) security guarantees at the cost of needed performance and functionality. For the first time, there is substantial industry demand for high-power, high-performance hardware that is secure under a comprehensive threat model.
