CYCLIC REDUNDANCY CHECK METHOD WITH PROTECTION FROM SIDE-CHANNEL ATTACKS |
| 摘要 |
The present invention relates to a method for processing a binary data item, comprising a step of calculating a cyclic redundancy check code for the data item by means of a generator polynomial, wherein the step of calculating the cyclic redundancy check code comprises the steps of: masking the data item with a random binary mask that is a multiple of the generator polynomial, and generating the cyclic redundancy check code for the data item from the masked data item. |
