The trusted platform always checks the access rights of all the applications that call the ND-security API to use the secure zone and can execute user authentication at the time it is required.
When the security application of the normal zone calls the NZ-security API in order to use the secure functions of the secure zone, the procedure of the TMZ system is as follows: first, the NZ-security API calls the TCM API with the access control data created by the AC agent.
The security applications of the normal zone (required to use the secure functions of the secure zone are accessible only through the NZ-security API. The trusted platform of the TMZ system is independent on the hypervisor type. ETRI's VIMO has the type 1 and type 2 hypervisors.
If the security applications and the user do have access rights, however, the SZ communication agent calls the SZ-security API in order to use the secure functions of the secure zone and returns the result value for the secure functions.
"You could make it compulsory for web servers to use the secure HTTPS prefix rather than the HTTP default," he said.
In contrast, with eDNA the user would have needed to enter a digital version of unique personal identifiers, like a fingerprint or voice, in order to use the secure enclaves of the network.
