This uses a TEE (a chip that is hard to take apart contain a private key provided by Intel), so the privacy system is very boring (they think the person who owns the TEE will not be able to see what the chip is doing).
- kaladin-jasnah 4y agoIs my understanding that a TPM is also a TEE correct?
- c7DJTLrn 4y agoTEE is more generalised, it runs arbitrary crypto operations. TPM offers specific cryptographic operations using the keys that it holds.
- jwlake 4y agoLook at this cool house I designed on sand. It's odd to design a secure system and write a paper, when the security is based on something like TEE. There's tons of literature on breaking TEEs. I can't imagine anyone doing other than checkbox compliance with that level of security.
- 7e 4y agoThe same could be said of cryptographic schemes and hashes in general—always being broken! However, that doesn’t mean TEE don’t provide a meaningful level of security, especially when combined with Shamir sharing between enclaves. Few actors will be able to compromise 100 TEEs distributed across the world and made by different vendors. And just like cryptography, TEEs are getting better with every release, and will soon be very, very hard to break.
- gsora 4y agoA TEE isn’t necessarily tied to any specific vendor, it’s a design scheme implemented by many different vendors in different ways. What you’re referring to is Intel SGX. There are open-source TEE implementations for e.g. ARM like OP-TEE.
