Abstract
A cryptographic device is configured to compute a target block cipher (Bt) on an input message and includes a control unit, and first and second block cipher units for computing the target block cipher (Bt) on the input message. The control unit is configured to take the first block cipher result and the second block cipher result as input, and to produce the first block cipher result only when the first and second block cipher results are equal.
