1. A fault resilient system comprising: a plurality of non-synchronized processor elements for requesting non-deterministic data; said processor elements operable to execute one or more processes; an assignment logic for assignment of non-deterministic data generated using at least one entropy source in response to a request for getting the non-deterministic data received from a requesting processor element, wherein said assignment logic comprises an entropy extractor operable to extract request variation data from any received request provided by processes executed by said non-synchronized processor elements.
