Abstract
An integrated circuit comprises a first processing unit and a non-volatile memory for storing a key. The first processing unit is arranged to carry out a cryptographic algorithm using the stored key. The non-volatile memory comprises at least two non-volatile memory elements, each memory element storing a share of a key used in the cryptographic algorithm. Each memory element is connected to the first processing unit by an independent bus.
