RSP (Remote SIM Provisioning) is an excellent mechanism for the delivery of sensitive data and that includes SIM apps resident within SIM profiles.
However, SIM/eUICC apps are still critically deprived of resources and... even strings... Even "large" eUICCs only have up to 1 MB of space (SGP.22 4.3).
This ETSI article may suggest that the eUICC could be resident within standard enclaves:
So could RSP also be used to deliver secure apps to standard enclaves?
And will SIM apps be able to take advantage of having a lot more resource, eg. resident within a Trustzone enclave?
Intel's SGX provides far more space, eg. 500MB and as high as multiple GBs, though as part of a server based Xeon chip. Could the eUICC be run in an Intel SGX enclave?
