摘要:
The invention provides a method for carrying out a cryptographic calculation comprising a plurality of blocks, in a manner protected against spying of secret data, using secret data in a processor. In order to achieve a calculation result, a multiple calculation is carried out, during which the calculation is carried out several times, at least twice. Within the multiple calculation, blocks of the plurality of, at least two, operations of carrying out the calculation are carried out in interleaved order.
摘要(中):
