Abstract: An apparatus comprises a logic processor and at least one hardware device the processor being configured to orchestrate at least one virtual machine, wherein each device and virtual machine respectively forms an isolated execution environment, the processor being configured to: generate a unique ID associated with the request for the result; commit to the unique ID; transmit to the data source the request for data, to trigger the data source to generate and return the result and to generate an authenticity proof of the result by leveraging at least one software attestation technique or at least one hardware attestation technique; verify the authenticity proof; and transmit to the remote application the returned result and verified authenticity proof. This apparatus can be used to provably enforce the correct execution of a given process without relying on the security of a single isolated execution environment only.
