The method involves performing an additional calculation by a verification function on an intermediate result to obtain a calculation signature. A part of the calculation is performed to recalculate the signature and compare them to detect a possible error. An elementary operation using another super-function operation is performed from a larger set. Independent claims are also included for the following: (a) an electronic assembly comprising storage unit of a calculation process (b) a computer program including program code instructions to execute the steps of securing an electronic assembly (c) a smart card comprising a storage unit of a calculation process. |
