ABSTRACT:
A method for securing a memory area comprising data blocks, wherein at least two control bits are associated with each data block, is provided. The method comprises a step of reading the control bits associated with a current data block intended to be replaced with the new data block, before the writing of a new data block in the memory area. A securing action for securing the memory area is begun if the two control bits have the same value. Upon each write of a new data block in the memory area, control bits having opposite values are written in the memory area. The method may be applied, for example, to the securization of a binary counter.
