Abstract
A method of and system (110) for controlled activation of at least one function in a product or component at a remote location, which activation requires a correct activation data item to be available in the product or component. The method comprises receiving one or more noisy outputs of an unclonable element associated with the component from the remote location, and providing helper data to the remote location, which helper data transforms the one or more noisy outputs to a single value which corresponds to the correct activation data item.
