Abstract: The present description concerns a method of checking a first data element, executed by an electronic device comprising a processor and a memory, wherein the first data element is divided in N second data elements being stored in the memory, and first data element being equal to the sum, modulo the dimension of a space comprising the first data element, of the N second data elements, wherein an image of the first data element by a LCG function is stored in the memory, and the method comprising a step of checking if the image of the first data element by the LCG function is equal to the sum, modulo the module of the LCG function, of a product of an integer varying from 0 to N−1 and an image of the dimension by the LCG function, and of the images of the second data elements by the LCG function.
