Abstract
An embodiment includes a processor coupled to memory to perform operations comprising: creating a first trusted execution environment (TXE), in protected non-privileged user address space of the memory, which makes a first measurement for at least one of first data and first executable code and which encrypts the first measurement with a persistent first hardware based encryption key while the first measurement is within the first TXE; creating a second TXE, in the non-privileged user address space, which makes a second measurement for at least one of second data and second executable code; creating a third TXE in the non-privileged user address space; creating a first secure communication channel between the first and third TXEs and a second secure communication channel between the second and third TXEs; and communicating the first measurement between the first and third TXEs via the first secure communication channel. Other embodiments are described herein.
