The method involves executing exponentiation of an element (201) pertaining to a group by traversing a set of bits of an exponent. Three registers are utilized to memorize values of the exponentiation. Occurrence of an error carried out after the exponentiation is detected (202). Result of the executed exponentiation is corrected (203) according to the result of detection of occurrence of error. Independent claims are also included for the following: (1) an electronic component (2) a computer program product comprising instructions for performing a method for performing cryptographic calculations in an electronic component (3) a computer readable storage medium comprising instructions for performing a method for performing cryptographic calculations in the electronic component. |
