Abstract:
1. A processor, comprising: a calculator for processing payload data using secret data representable by binary information units; a plurality of electronic fuses for storing the secret data, wherein each fuse of a plurality of electronic fuses is implemented to store, in an integer state, a first binary value for a binary information unit, and to store, in a non-integer state, a second binary value for a binary information unit, wherein the first binary value is different from the second binary value, wherein the binary information units are so that they constitute a redundant representation of the secret data, and wherein the plurality of electronic fuses is adapted to store the binary information units, and a reader for reading out the plurality of electronic fuses in order to determine the secret data, wherein the reader is adapted in order to perform an error correction on the basis of the redundant representation of the secret data, whereby a binary information unit of the redundant representation of the secret data, which is stored by an electronic fuse being in an erroneous state, is corrected.
