According to a method, a request for execution of a task is transmitted by a first apparatus and to a second apparatus, the task comprising a plurality of functions to be executed.

An execution result for the task and a second validation key are received from the second apparatus. Correctness of the execution result is determined by comparing the first validation key with the second validation key. Through the solution, it is possible to provide the verifiability of the correctness of the execution result returned by the remote apparatus and achieves high performance on security, trust, and privacy.
