I sent below question at https://software.intel.com/en-us/forums/intel-software-guard-extensions-intel-sgx/topic/734606 .
But it is a little different theme of my question.
So I make another subject.
I understand that the design concept of SGX and TrustZone is a little different.
However, I think these function is almost same.
So my question is that ``can SGX equipped devices attest TrustZone equipped devices?"
#Can Remote Attestation work correctly?
I think this is very typical case of IoT systems.
(Intel CPU is installed in IoT Gateways, and ARM CPU is installed in IoT devices)
I read many journal articles and whitepapers, but I can't find information of it...
Do you have any ideas?
Thank you for your reply.
The reason of it is that ARM TrustZone does not implement the attestation, right?
In other words, if the function of remote attestation is implemented in the TrustZone, can SGX attest the TrustZone equipped device?
Hi ryo hamamoto
I think what you said is right. If you write your own code to implementing the functions. You can do what you want. This link
But I'm not sure.
Thank you for your information.
I check your kind reply.
In order to solve my issue, I understand that an implementation of attestation function for TrustZone is required.
