Abstract
A method for secure data reading and a data handling system is provided. The method protects the data reading from fault attacks by repeating read request in an interleaved manner, in particular the method comprises the steps of (M) dispatching a first read request; (M) dispatching a second read request; (M) dispatching a further first read request; and (M-) producing an anomaly signal if a first result produced by the memory in response to the first read request does not agree with a further first result produced by the memory in response to the further first read request.
