摘要： There are described methods and apparatus for enhancing security when executing a computer algorithm comprising separately executable tasks, each of which produce an electrical signal when executed. The apparatus comprises memory in which at least part of the computer algorithm is stored as at least one pipeline, wherein the at least one pipeline comprising a plurality of separately executable tasks; and a processor. The processor is configured to receive a plurality of inputs to be processed by the computer algorithm; randomise the plurality of separately executable tasks at a pipeline level and/or at a task level; execute the randomised plurality of separately executable tasks, and repeat the randomising and executing steps until the computer algorithm has processed the plurality of inputs. In this way, at each repetition, the electrical signals produced when executing the plurality of separately executable tasks are randomised to enhance security.
